I worked for one of the Canadian carriers, and they are only not a monopoly as far as the paper definition is concerned, but in practice they do in fact gather in smoke-filled rooms and decide to screw their customers (your words, not mine). They are also very good at pretending they don't.

Apple on the other hand has created an infrastructure to enable a billion interconnected devices, and they are now charging a fee to operate. They are not colluding or preventing competition, they are simply saying there's a price to play, and it's 30%.

It's natural that Fortnite doesn't want to share their profits, in the same way that Apple doesn't want to be the only ones taking the loses, but every time this question comes up, lots of comments assume Apple should bend over simply because it's bigger and wealthier.
