Apple need one of these https://learn.microsoft.com/en-us/openspecs/
I buy Apple specifically because I want the level of privacy that their platform provides. If third party devs don’t like it, they can ship for Android.
I'll just leave you with the fact that Apple across two decades paid pennies in taxes in Italy (claiming few millions in revenues) because they would have bullshit like Apple Ireland selling Apple Italy iPhones for 1000€s and selling them for 1000€s plus vat.
Meanwhile Apple Ireland was buying those iPhones for the pennies it costs to make them (few hundred $ at best) and thanks to Irish corporate taxes being close to non existent (0.5%) Apple has paid virtually nothing for decades.
If you believe that us European voters love our countries to be subsidized by rich American countries you're out of your mind, but what we dislike is being taken advantage over and over.
Privacy is about making access transparent, not by having customers in tiers.
I swear there's a parallel world with lunatics saying they are glad that only XCode can access their file system and processes and they don't want that Vim, VSC, Emacs or IntelliJ crap.
