I gave it another try last week

• the onboarding automatically creates a username/password on the server you selected, more details here: https://chaos.social/@delta/115479392746850836
• E2EE using openpgp
• fast and light on resources

It's still in development, it's not a fully fledged replacement for Matrix yet, but I could see it replace Signal at some point.

Linus videos have clickbait titles like that, and it's in reference to some news articles calling GOS an OS for criminals

Title and thumbnail aside, the video was a positive review of GOS and was made with help from a GOS team member. I probably should have added the extra context before it got downvoted away 😄

How people talk about data privacy can overcome – or reinforce – their skepticism that things can change.

Introduction

I wanted to explain the structure of freedom, and why part of what constitutes a free society is the right to privacy. One of the most difficult parts of educating people on privacy is the confusion about what it actually is. People often confuse privacy with secrecy, privacy with anonymity, and privacy with security. I want to distinguish between multiple related terms and show the structure of how, in order to have a truly free society, you need the right to privacy.

What is privacy?

I want to be very clear about what privacy actually is and is not. Privacy is not hiding everything about yourself. Hiding things is secrecy. Privacy is not hiding who you are. Hiding who you are is anonymity. Privacy is not protecting your information. Protecting your information is security.

Privacy is the ability to choose what you share. That gives us our first clue about the structure of a free society. Secrecy relies on privacy, because if you can't choose what you share then you cannot keep secrets.

An example of secrecy would be hiding how much you make at your job. An example of privacy is choosing to exercise that secrecy. In the moments between someone asking you how much you make and telling them you don't feel comfortable sharing that, you take a moment to decide whether or not you want (or consent) to telling them. That is privacy.

Why the distinction?

The distinction between privacy and secrecy is incredibly important for making arguments about privacy. People may say "I have the ability to choose what I share, because I am able to choose your level of privacy if I want to." What they really mean is that they can choose your level of secrecy. You don't choose to be under surveillance, but you can choose to protect yourself from surveillance, not by hiding everything you do but by eliminating the things that are tracking you in the first place.

In reality, many people cannot choose the same level of secrecy. Privacy is eroded in the background, and many people don't realize how far surveillance really goes. Becoming secretive is not the solution, because that is the same as eliminating your free speech in the face of being persecuted. This is our second clue about the structure of a free society, because free speech relies on both privacy and secrecy.

What is security?

Security is, simply, measures taken to protect something. Encryption is an an example of security, because it is used to protect sensitive data from unwanted intrusion. I want to make a clear distinction between security and safety. Security protects you before an intrusion occurs, whereas safety protects you after an intrusion occurs.

An example of safety is a surveillance camera. A surveillance camera cannot stop a crime from occurring, but it can record evidence to convict a criminal after the fact. On the other hand, strong locks are an example of security, because they protect a store from being broken into before a theft takes place.

I deliberately call them surveillance cameras instead of security cameras, because safety is different from security. When the news talks about security measures, often times they are really referring to safety measures. Safety measures are often privacy invasive, because they usually require a level of data retention to be effective.

Security protects against unwanted intrusion. If there is unwanted intrusion on data, that means it was shared without consent. Because of that, if there is no security, there is no privacy either. That gives us our third clue about a free society. A free society does not need safety, it needs security, and privacy is not possible without security.

What is anonymity?

Anonymity means hiding your identity. Because it directly relies on hiding something, it's immediately obvious that anonymity relies on secrecy. Anonymity is the best defense against a corrupt government, because it allows us to speak up against corruption without fear of persecution. Even with perfect secrecy, we ourselves can still be convicted by exercising our right to privacy. This is the final piece we need to see what a free society relies on, because without a way to combat corruption, there is no way to be free.

What is freedom?

We've finally arrived at the final section, which puts together the pieces to show what is necessary for a free society. While this is only part of what freedom requires, it is not a part that can be ignored.

This pyramid of freedom shows the dependencies for each element. Security is the foundation that everything else is built on. Privacy relies on security to prevent unwanted violation of consent. Secrecy relies on privacy to prevent sharing without consent. Anonymity relies on secrecy to hide your identity. Finally, freedom relies on anonymity to fight against corruption.

You may notice safety is not on there. While safety can be good, it often violates some aspect of the pyramid. It isn't necessary for a free society. In fact, safety doesn't even need security. Surveillance cameras are breached all the time, but that doesn't change their purpose or effectiveness.

Conclusion

Privacy is essential for a free society, but it isn't the only essential liberty. Security is the foundation that privacy is built on, and even that is eroded away by conflating security with safety. Knowing the distinctions and relationships between the various elements is incredibly useful when speaking up about privacy, because even if you can defend every "nothing to hide" argument, people still tend to have a fundamental misunderstanding about what privacy really is.

Lack-of-AI Notice

I've been burned before, so I always try to mention that none of my content is AI generated. It isn't even AI assisted. Just because something is comprehensive and well-structured does not make it AI generated. Every word I write is my own. Thank you for your understanding.

This was my first time testing an easier way for me to create posts by first drafting them in Iotas. I had a couple hiccups such as forgetting to insert the image and forgetting to double newline paragraphs, but it worked alright.

How can I check to see if a given Onion Service is still in-use?

To be clear: I'm not asking about just Onion Services bound to port 80. Of course I can just curl it, but that won't tell me if the Onion Service is running something on another port.

I'm trying to find an XMPP server that uses an Onion Service. I found several lists of XMPP servers and their .onion names, but I expect most of these services are offline.

I don't want to eliminate them just for not running an HTTP server (eg port 80, 443, 8080, etc). Nor do I want to eliminate them for not running on a common XMPP port (5222, 5223, 5269, 5298, 8010). I'm trying to find something that checks if an Onion Service has been used in the past days/weeks without requiring me to test a connection on a given port.

My understanding is that Onion Services will (by default) generate and publish hidden service descriptors (HSDir).

Is there some way I can query the Tor directory of HSDirs to see if a given Onion Service is still active?

They have a hidden app with every permission enabled already and you can't change that.
