No, it is literally not. Music streaming services were specifically excluded in the legislation, and they set the revenue requirements way higher than Spotify's revenue to ensure they wouldn't get hit.
No, it's following the letter of the law. If the EU didn't want Apple charging apps using third party app stores fees for using Apple's intellectual property, then they should have banned charging of said fees, not say "wait, that's not what we meant so the law says something that isn't written into the law".
(Side note: complying to the least extent possible allowed by law is not malicious compliance. Malicious compliance would be "fine, we're not doing any security screening on any app downloaded anywhere except the App Store, and if an EU citizen gets their accounts drained or their phone hosed, we're going to give them the phone number of their MEP and tell them to complain to the politicians who required opening up the walled garden to virus developers and scam artists."
Agree here absolutely. It's for the courts to decide.
People arguing that the GDPR was good will never not be funny. Your regulators made the internet so much more annoying to use. Yes, we know cookies exist, thank you EU. Example #1 on how the EU clearly can't think through the consequences of their overbearing regulations.
