This would kick the wasp's nest of "they (Apple) don't need this much money to operate, they can do well with 10% profit!"

Which is very hard to admit, that profit margins are arbitrary when you, indeed, dominate the market.

Apple doesn't want (nor need) to give anyone a handle to anyone to make them accountable. It is not a charity.

(Again, I'm not defending Apple, but I do defend corporate liberties, in general.)

Apple is honestly worse than Microsoft in so many ways as far as restrictions (nowadays, anyway) and yet it's taken this long even to get here.

(To be clear, I am not a fan of Google's actions in the mobile space either...)

It is about illegal anticompetitive behavior.

Apple didn't charge tax on all app store purchases to protect themselves, it was done out of greed and malice.

You're assuming that Apple is acting in good faith. An actual, literal judge has decided the evidence shows that Apple was not acting in good faith, and in fact were behaving illegally. This isn't a "both sides" argument, Apple is definitively in the wrong.

Another word for that is "competing". And yeah, exactly.
