I mean there’s Reddit ofc, as well as Twitter in its entirety, Discord is implementing some dumb updates, there are issues with Tumblr as well as everything to do with Meta, and I’m sure there are plenty more (and I haven’t even touched other digital media, for example the Sims). Why is it all happening in the span of about a couple months?
Lemmys developers mostly fund themselves by a grant of the Dutch NLNet Foundation, they have talked about it in the past.
