I was mostly just having a bit of fun and obviously your statements get more to the point. Keep in mind that the commission sets the playing field. The telcos (on queue of course) are there to try and abuse it. I'm sure the concept of "digital sovereignty" is noble and makes sense on the surface, but unintended consequences seem to bite hard.
You are absolutely right saying "digital sovereignty" is not a completely clear concept. The telcos seem to stretch it in a very surprising way.
The official and original idea behind digital sovereignty in the EU is to support individual's control and self-determinism over their own data. The opposing forces — as they are usually seen — are governments and companies. The EU approach has been seen as the "third road" between US's surveillance capitalism and China's tight control. (Probably because we missed the train with the first one and don't really want to take the second one.)
In practice, there are several forces pointing to the same direction:
- commercially motivated opposition against MAANA (Meta, Amazon, Apple, Netflix, Alphabet)
- fear of espionage from outside of the EU (I may not need to name the suspects)
- true privacy ideology
- putting citizens in control of their data because citizens like the idea
There may be others, as well, but most reasons do not apply to the private relay. The only thing I see is that Apple needs to prove it stores the traffic information (end-user IPs) within the EU.
Different EU countries and different political powers have different concerns and reasons to support digital sovereignty. Some European countries are very concerned about privacy for historical reasons. The very long shadows of the WWII are still there. Some European countries have a relatively flexible interpretation on what is personal data.
Despite these differences in interpretation, the "official Europe", i.e. the European Commission, has usually had a strict view on privacy. If the ideas of digital sovereignty and net neutrality are combined, the telcos' chances of banning Apple's private relay resemble those of the proverbial infernal sphere of compacted icy precipitate.
The EU will, naturally, try and find any good reason to make Apple's life more difficult, but privacy aspects make it very unlikely in this case. (Personally, I find it almost surprising the telcos want to take the risk of drawing attention to their actions. This may trigger some unwanted questions about what they really do.)
