Because it's anti-competitive. Society is advanced when companies have to compete and not just collect taxes from other companies who are trying to do something.

The Apple tax is not advancing anything. It's just a stranglehold on innovation promoted with FUD about how running programs is insecure despite the fact that this isn't applied to desktop/laptop computers.

If it's such a stranglehold on innovation, Android will out-innovate and outcompete iOS.

Or maybe Apple provides a platform that some users and businesses still find it worth paying for.

You're arguing for the government to ban products you don't like when you can just buy something else.

Apple developing a more secure platform is an innovation and advancement. If the iPhone isn’t the right choice for you buy one of the other thousand phones on the market, and leave other people alone.
