This forces browsers to accept all the CAs approved by the EU states, and you can be certain that some of them will be used for decrypting (and if needed modifying) the traffic
And then you can just tell the browser to not trust those CAs and you are safe. This is nothing like "chat control". This only lets the government spy on people who don't care if the government spies on them.
Why shouldn't you be able to do that? Seems like a simple thing to implement. I get why they want a hardcoded list, but I don't get why you can't add a way to block parts of that hardcoded list.
