No.
Interoperability is only required, if you have a significant market share. Apple does not have this in the EU. iMessage specifically doesn’t fall under this regulation, since hardly anyone uses it.
And since Apple plans to publish an SDK for their intelligence anyway, you can’t really regulate them for being too closed.
So either that’s a purely political retaliation, or their “super privacy friendly” services aren’t as privacy friendly as they claim.
I find it really weird that something as simple as the basic functionality of nextcloud seemingly can’t be implemented in a stable and lightweight manner.
Nextcloud always seems one update away from self destruction and it prepares for that by hoarding all the resources it can get. It never feels fast or responsive. I just want a way to share files between my machines.
There are other solutions, I know, but they’re all terrible in their own way.
