They’re not actually relinquishing any control. They’re just allowing subsidiary “app stores” to take a tiny cut while Apple still controls everything.
I’ve been an Apple fanboy for years, but less so these days. I can’t imagine that the EU won’t fine them for this, although it’s hard to imagine any fine that would make an impression on a $3 trillion company.
No. Moneyory fine should not be a form of punishment. I am for old fashioned style, an extreme example is to call the CEO, make him dance around the EU naked and then make him collect the shoes while returning home.
