In practice users don't really choose which CA to trust. That choice is made by app and/or OS developers but I understand your point. That EU directive seems to force developers to accept EU's CA which is wrong of course.

Nevertheless this CA store distribution put us in this censorship situation. I think it should be moved further towards the service provider in a similar way webauthn works. The 3rd party CA makes the whole process vulnerable to rough CA providers or mandatory CA stores. Let's stop trusting 3rd parties with our security.
