you've seen nothing. Tomorrow it's gonna be all over lemmy again "hello I'm a refugee, how is lemmy profitable without ads?", or "admins should make sure we have this thing X like on reddit"
FWIW I deleted my Reddit accounts on 6/8 and started checking out Lemmy this week after a couple weeks of sorely missing Reddit and trying to make other platforms fill the void.
I believe I may be uniquely able to comment on this, actually. I managed a technical support team as our company discontinued our old app, which was still much loved by a subset of our users. They were NOT happy about it.
Almost all of the changes happened prior to the final date that we communicated. Everything kind of shook out before then - users either moved to the new app, or left us completely. We expected there to be more of a shuffle on the final date, but almost nothing happened.
Maybe it will be different here? You could say I had Reddit HQ's perspective, rather than Lemmy's, and that I wouldnt hear much from the people that just left, which may be true. I hope so.
