QWAC certs are only for "high value" sites: banks, government services, etc. They can only be issued by "Qualified Trust Service Providers" (e.g. digisign, D-TRUST, etc -- not governments), and cost many hundreds of euros. Your blog and mastodon instance and 98% of businesses just aren't affected.
People operating in "high risk" sectors that need access to payment infra (porn, drugs, etc) are, as always, going to have a hard time. That's a worthy conversation, but nothing about QWAC or eIDAS is about "the government not issuing certs to people they don't like".
Secure Boot is just a technology for those that need it, until Microsoft decides it's mandatory for everyone.
