That remains to be seen, and, if developers abandon the Apple app store, the damage will be permanent. Moreover, it only takes one corrupt source to infect a system with a computer virus. Finally, as many of you have pointed out, consumers already have a choice: they can choose Android and side-load to their heart's content. I don't understand why the EU got a burr in its saddle about Apple given that the EU mobile phone market is dominated by Android (see

The governments of 27 countries or the people of 27 countries? There is a difference. I see political petitions all the time, but none have been about Apple's app store. I was in the EU for two decades but then the UK voted to leave (not something I supported and I wish Scotland would rejoin even if it means splitting from the UK). Still, what the EU does affects everybody on the planet, unless you are willing to allow Apple to disable side-loaded apps when consumers are outside the EU.
