Guys what did I miss? Why did so many people move to Bluesky? I’m not complaining but what prompted it?

I figured that a lot of people moved because Elon is an asshole. I just don't use Twitter anymore and wanted to see what was going on over here.

Afaik it’s a mixture between Elon changing the way blocking works (which will have Twitter banned in several countries including Canada) and people discovering that Twitter automatically trains its AI off of your posts without any warning or way to opt out
