I don't think you're grasping the point of antitrust. This was a common sentiment about AT&T in the 70's; people actually liked them despite their monopoly because they liked having telephones and didn't realize how much better things could be.
Yes, Apple is fricking expensive. Yes, I'd prefer if they would offer something at cheaper price points. Yes, I'd prefer if they were forced to provide better-than-mediocre software. Yes, I'd prefer if there would be access in case things don't work, for me to fix stuff myself and not just shrug and try again. BUT they are still without a reasonable competitor that manages to even meet their bar in quality. And yes, that makes them comfortable enough to behave stupidly and in (more or less) open ignorance of anticompetitive regulations. However making their offering _worse_ is not helping _me_! Demonstrate a similar amount of customer safety and we can talk about mandating that also for Apple. But thanks but no thanks if the best we can hope for is AndroidII
