In that case, I feel bad for you and am glad you found another instance.
Left or right, at some point telling other people what they can and can't do is a bad thing. I would absolutely agree that the data scraping that AI companies do is a bad thing, but I don't see how my joke pictures of #JohnMastodon actually hurts artists enough to ban the practice. Now, an art gallery or magazine, that is another thing. But I digress.
I do think as we get many more larger more "open" instances, like Vivaldi, that kind of experience will become less likely.
On the positive side, I have seen very good evidence of very cool instances -- for example there is an instance for people who like type fonts, more organizations now have their own instances and so on.
