It isn't proprietary either

What part of Matrix is proprietary? It's not an app, instead, it's an open protocol that can be used by anyone to build a messaging app or host a server.

Discord is an absolute piece of garbage, it's not a good messaging app, definitely not a good place to host a community (seriously, I don't understand why some communities saw Discord as an alternative after the Reddit API changes), and most importantly, it's spyware. The company doesn't have a business model and it was founded by a guy who is notorious for creating random shit that's not economically sustainable at all. I don't understand why anyone would use this shit. This video outlines everything that's wrong with Discord: https://youtube.com/watch?v=uvNkdAggUGU

Switch to Revolt or Matrix

Linux Mint is awesome for beginners.

Am I seeing Reddit there?

I remember using this (cheating a little bit with VPNs and proxies so I could claim the rewards like 20 times every day, because they are separate in every country) to get some Xbox giftcards

I also had ~15 Microsoft accounts and I put them all in a Microsoft family so I could transfer points from one account to another, it was really fun lol

Edge is the worst recommendation I've ever seen in my life

Linux isn't Unix, it's Unix-like

Using Signal with disappearing messages set to a really short time is probably the closest thing you can get. You can use a VOIP number from Cloaked behind a VPN to sign up anonymously.

I love GrapheneOS and they tried everything to make Chromium less shitty, but Vanadium still lacks fingerprinting protection as well as support for ad blocking. That's why I use Mull, a hardened fork of Firefox, for everything except banking.
