alt Hacker News> What worries me is that Google has a fairly legit argument to say "then Apple should as well".
Not a legal argument, since Apple never claimed the iPhone was anything else but a walled garden, and walled gardens are legal as long as you are clear that users will be buying into a walled garden from the start.
(For example: Nintendo, PlayStation and Xbox)
Legally, the only thing you could do is change the law to make walled gardens illegal, as they did in the EU.
The changes Google has proposed for sideloading are illegal under existing law, since Android was sold to consumers with the promise that it was the "open" platform that allowed users to run anything they like.
That argument would only last as long as current Android devices are supported for. In seven years, the last devices will run out of support and we'd be back to square one
Legislation, as you say, seems like it'll be necessary :/
