Isn't WireGuard post-quantum safe with pre-shared keys?

HTTP3 over QUIC is blanket blocked in many countries (due to QUIC's built-in censorship resistance).

Probably not post-quantum safe. The first standards just came last year. And there are still arguments that these standards are not good enough. Some were compromised already.

Edit, correction: the one considered standard algorithm was broken https://www.theregister.com/2022/08/03/nist_quantum_resistan...

And yes, anything which uses symmetrical keys is post-quantum safe. But you can't always use them and there are other problems.

every one of these statements needs an authoritative reference

I'm guessing WireGuard PSK is post quantum safe, because it doesn't depend on a private/public keypair?

Could you please explain what does it mean in PSK context? Any relevant link.
