> Granted, Apple generally doesn't do that last part unless forced

which is the point here.

If they made a new feature, something AR based, they are totally allowed to build that and keep it relatively private for a few years. What they can't do is when competition appears, actively keep them off their platform. For example if a device manufacturer manages to make an AR device that works well with android, but its impossible with apple and apple have significant market share, then that would be illegal.

The point of this is to stop thiefdoms and to keep innovation. You're allowed to have a competitive advantage, you're not allowed to build a monopoly.

(if we look at defence, budgets are still very high, but the rate of innovation has plummeted compared to other industries. Its only now with the spur of VC cash into non-traditional backgrounds are we seeing innovation again)
