I agree that Apple does have that monopoly. I guess the difference is that Google actually does technically allow third-party app stores, but used their monopoly position to squash them, at least in the realm of pre-installs?

I'm not sure why this should matter, though. I don't see why it's somehow better to use technical means to refuse to allow there to be a competitive market, than to use shady business deals to ensure a competitive market doesn't grow.
