I don't think OS vendors should be expected to keep people from doing dangerous things. A warning label saying "hey that's dangerous because..." is reasonable, but anything more and they're trying to be my sysadmin against my will.
These are sold as consumer devices and not general computers. It sounds like you want something different. They’re selling cars and you want a motorcycle.
More sysadmin-as-a-service type stuff is fine as long as the opt-out is easy. This isn't. I'm upset about the rug pull.
You never know though. Sometimes things go the other way. When the iPhone launched there was no way to create apps for it or install third party applications except as web apps.
