I mean, maybe it's because I'm not overly paranoid or live in the US, but this doesn't seem like a big deal at all.
As for the "drama" of them telling someone they can unfollow, it's true. It's again, not a big deal.
This screams people trying to make a mountain out of a molehill.
lemmy.world is probably overloaded.
On my instance, everything from them floods through all at once, filling my first couple of pages with hours or even days worth of stuff, then I'll get nothing from them for a while again.
