Apple takes many anti-competitive and consumer-hostile actions. They can freely get away with it, though, as they aren't a monopoly.

So, forcing them to give users a choice is somehow equivalent to... forcing vendors to not give customers a competitors browser?

Ok sure. That seems totally the same. Not at all as ridiculous as the invented "monopoly of iOS" that people use to justify the claim Apple is abusing a monopoly position.

Next thing you'll complain Coca Cola is abusing its monopoly position on Coke.
