This works if we're only talking about static images.
However, if a thread links to, let's say, something from redgifs.com, then you'll only get the static image instead of the animated gif that you would hovering over a direct link.
Do you know how we can reach the underlying linked URL and use Imagus based on that?
There is an option that reddit has zero ability to stop:
If redditors band together and commit to boycott any company who advertises through reddit until reddit reverses their changes.
Companies have been very careful about trying to not get tied into the protests. But now we make it so that reddit is poisoned fruit.
There is nothing reddit can do to stop this. No rules they can change to subvert it, because we can publicize this boycott on any and every other platform if they try to silence us.
Boycott companies that advertise through reddit, and that will throw a major wrench in their current income as well as further sour their IPO prospects.
