@foone I think your point is good but I want to note one special case: A lot of Japanese artists seem to be jumping to Bluesky right now, and I think the reason they're jumping to Bluesky right now instead of Mastodon is that on Mastodon you can get banned for being Japanese* and this is not true on Bluesky.
* Read: "Banned for being federated with a particular large Japanese server". This was as far as I understand a very real problem at one time, I do not for a fact know whether it still is.
