Not now.
A company that is fully vertically integrated, isolated, rich, powerful and market dominant is exactly what the EU likes to go after as we've already seen in the past.
You can't make vertical integration illegal, hope I'm not laying a curse by saying that, but what it does do is strengthen Apple further and that begs the attention of those who would seek to weaken it or milk it.
Didn't the EU just pass a useless law about USB C charging ports for phones when the mobile phone tech has been moving to wireless with Qi as standard? Who was that aimed at?
Hasn't S.Korean just legislated allowing any in app purchasing method?
Didn't Russia pass a law about state approved default apps on mobile devices?
The list goes on and will continue to grow.
How long until the EU thinks up a good excuse to fine Apple $billions for some rule breach, or creates a law just to take a bite out of their a$$.
