As usual doing malicious compliance, like when they pretended that iOS and iPadOS were two completely separate operating systems and so iPadOS shouldn't need to support third party app stores as EU said "iOS"
Probably because there aren't any, they can't specifically say "iOS".
I'm not aware of any other operating system (except the ones in game consoles or dedicated hw) that doesn't allow the user to install other software not approved by the manufacturer
Actually the more I think about it the more it seems like the only, legally fair decision. Either all of them are demanded to allow alternative app stores or none of them are. Why should the consoles be any different in this regard? 🤔
