I personally am quite against it. I joined Lemmy to stay away from the toxicity on Meta's platforms. I don't want any corporate bodies on the fediverse either and possibly doing to the fediverse what Google did to XMPP
Honestly - good. If that keeps the “normal” users on that platform, which will likely be defederated, I’m perfectly fine with that.
There’s a large population difference between the current fediverse and XMPP in the past. I think there are enough people who would stay on the non-mainstream platform to keep it alive.
