It's funny how pointing a fact is called whataboutism.
You trust the EU's pinky promise a keep their word that your ID will be safe and secure and never tied to what you say, the content of your messages or who you send them to. If that is so, then go ahead and use it. That's your business.
> whatever negative aspect
The EU literally wants to read your personal messages because it doesn't trust that you are not some criminal in disguise. Instead of the state having to prove that you are criminal breaking the law, it wants to read everything you send and store the data permanently in case you break the law one day. If you think that is acceptable and that is an entity that can be trusted, then I don't know what to tell you.
If I understand correctly how this works, it doesn't require trust or knowledge. The service gets exactly 1 bit of information (over/under the required age), the government system gets nothing.
"Don't trust, verify". It is an open protocol based on cryptography for everyone to verify that simply does not allow to submit identity information when you perform the age verificaiton check. There is no opinion here, no "you have to trust X not to do that later" - it is the property of the used technology to just submit the verified age. You can't derive identity information now or in the future just if you age-verified yourself. You are being paranoid and talking about a fantasy, non-existing system that is not the one I linked to.
On a side note, whataboutism is not about "stating a fact". It is when the stated fact has nothing to do or does not interfere with the original point being made. As in "Why would I trust the EUDI act when the EU does shenanigans like come up with stupid norms of the shape of bananas" - Stated is a fact, but it has nothing to do with the actualy EUDI act.
At this point, it's just something stupid people say. It used to mean that when you pointed out that my people were desperate for the freedom of living under capitalism, I would point out that you lived in an apartheid state.
Somehow, here, "whataboutism" means that if after you point out that the EU is coming up with an age verification system that they claim preserves personal privacy, I point out that the EU is also very much, openly, against any sort of personal privacy. Somehow that's some form of communist propaganda. Or Russian propaganda. Terrorist? Whatever. The important part is that I'm someone who should be watched or arrested if I continue to question your motives on behalf of our enemies.
