I purchase Apple products for their walled garden ecosystem. Vetted software and all that. If I wanted third party software, I would've bought an android. Simple as that. iOS is a walled garden since 2007 and Android is third party friendly since 2008. The market knows this and makes choices based on these facts. EU is just trying to hurt Apple and in extension the U.S because their only chance at the smartphone and broader technology industry, Nokia, was gutted by Microsoft, a US company.
By the way, If you want to run 3rd party software on Apple products, then no one is stopping you from buying a mac.
2nd hand m1 mac mini: 250
New m4 mac mini 499-599
New m4 macbook air 850-1000
as you can see, the bar of entry for 3rd party software on apple platforms is pretty low.
I understand your point, yet it is biased in Apple’s walled garden favour.
Right now nothing is stopping you from continuing using Apple’s own walled App Store exclusively, as you like it, so your bases are covered. Yet there are people who would like to install their apps from other stores/devs at their own risk, so why deprive them of this choice?
And some of them do not want to use Android (else they would already), nor can they fit a Mac in their pockets. 😉
