Lemmy is a reddit-style forum framework on the fediverse. People clone a copy and launch their own instances which can communicate with each other, so that no one person can rule over it.

So theres these guys who want China to win a nuclear war and the enslavement of trans people into labor camps, Lemmy ML and Hexbear. They are the Lemmy Developers and all money for lemmy development goes to them.

Then theres this Rimu dude who started development of PieFed which is just another framework to do the same exact thing that Lemmy does and they communicate with each other flawlessly, which makes the Tankies super duper angry because they wanted you to fund their autocratic ideology and help them spread propaganda.
