Apple should be punished for this more than Google. Google doesn't ban competing browsers, Apple does.
On Apple, I think the EU will do a better job as for better or worse there will be no "let us bring money to the country" defense like the last time.

And what is the definition of nasty here? It's very subjective. Apple doesn't own the mobile market and are below 50% control of it so they are not really a monopoly. I'm also not sure how you can use anti-trust or anti-monopoly against them when they have been found again and again to not be a monopoly.
