I run my own instance just because I want to build a community that people can enjoy. I do it out of my own pocket and don’t ask for donations of any kind. Not everything is about profit for some people. If I were running a site as big as Lemmy.world, then I would consider it, but only to cover some expenses.
Not as many as you would think. I work in a technical field and most people had no idea there was a protest going on. They also didn’t even know of alternative mobile apps. Most didn’t care and just used the official app. There may be a slight bump, but nothing significant.
Like others have said, nothing is stopping them. That is why it is important to spread communities around to other reputable instances, so if something like that does happen, only the communities on that particular instance are lost.
