The thing is, Europeans are mostly annoyed with Apple over this, not the EC.
It just reads like arrogant foreigners throwing a tantrum over our laws.
I would call those people uninformed. It's completely reasonable for Apple to be hesitant to roll out any new integration features within their own ecosystem in the EU.
iPhone mirroring for example. Seems like practically 100% chance that if they put that out in the EU they'd be facing lawsuits for not making it work with every Android and Kindle and digital pregnancy test on the planet. And making it an open API right out of the gate is a much bigger undertaking than just making it work with your own devices through a proprietary API that you're free to break at any point and just update your devices to work accordingly.
I struggle to believe there isn’t a significant fraction of EU citizens who are frustrated with the EU’s laws.
At the very least to the extent that the whole setup limits national sovereignty.
Your comment comes across as though you expect us to believe EU citizens are a homogenous whole, who happen to align with your perspective on this matter.
