This was not always the case. What’s stopping a competitor from defeating both Apple and Google? Windows Mobile had a peak market share of about 42%, higher than what Apple has in the EU.
My response to B is the same to A.
Regarding C what is an acceptable percentage - how did you come up with that number? Apple has been pretty transparent about the rules - why buy if you don’t like?
Globally it peaked at 4%: https://en.wikipedia.org/wiki/Usage_share_of_operating_syste...
I disagree. Apple doesn't let App developers to inform users about the 30% tax. How is that transparent?

It’s not a secret at all, lol.

The issue you’re describing is more of whether Apple should allow App Store developers display messages to the end user of their apps saying that Apple is skimming off the top. Similar to how it would be if Apple said Visa will take 2% or whatever.
For example for currency exchanges we had laws(in Romania) that you have to print in giant fonts all the fees/taxes. The law was created because the giant text was showing some values and the fees were hidden or printed in small fonts somewhere unreadable.
IMO aa country could force Apple to print on their iPHone boxes something like (30% of your subscriptions or Farmwill gems go to Apple, buyer be aware that you can probably buy the subscriptions cheaper on the developer website but Apple won't allow them to show you the link because they are greedy)
Can someone kept in the dark by App Store rules even know that he is screwed by Apple?
If Apple is harmed by this can chose not to sell in EU.
The developers are creating value for Apple by improving their app ecosystem but Apple is acting like they are doing the developers a favor.
