My entire tech bubble moved to mastodon and it's been great. No ads, no algorithms. Maybe the VC bubble is just stuck with it because of what it used to be?
The non-technical tech sphere hasn't really moved though, but maybe my circles are quite different to yours.

That's not really how it works. Federation happens ~by default in general; restriction is reactive, not proactive.
But you still breathe, right?

(The dynamic is very different when it's voluntary and feels like supporting a community, though, and in practice it's going to be a few whales making donations)
