I hate AI and Microsoft as much as the next guy, but to me, this looks like a grey area. The name and logo (all most people will see of this account) aren’t really clearly parody… there is a faint smile in one of the squares, but at 16 pixels tall, you’d never see it.
“It came from somewhere else so I don’t have to respect a takedown notice” is not a valid defense.
This is certainly an interesting hill for the fediverse to choose to die on.
This could be an intentional first attack by big tech to get a knife into the fediverse. Showing a judge blantant disregard for takedowns isn’t a great look, and they have a LOT of lawyers.
