I've been trying it out for the last week. I have my own opinions, but I'd like to hear others and see if we have common ideas on what is good/bad/indifferent about the Lemmy ecosystem.
If a billionaire buys LW tomorrow for a few millions because they host most of the Lemmy active communities and users, and prevent instance migration overnight, how many users are going to go through the hassle of creating new accounts from scratch, create new communities? That could kill the platform, with the LW starting to show ads and only being compatible with an enshitiffied app, so most users would probably go back to Reddit.
Also, there has been some concerning behaviour from LW mods, which know they can just go with it as people are already on their communities and are not going to move: https://lemmy.world/post/20947890?scrollToComments=true
