> In addition to the cookie privacy pop-over when viewing that site

I don't know where you're seeing that as the site does not have such things. The only cookies present are essential and so nothing further was needed.

The site does not track you, sell your data, or otherwise test you as a source of monetisation. Without such things conforming with cookie laws is trivial... You are conformant by just connecting nothing that isn't essential to providing the service.

For most of the sites only a single cookie is set for the session, and for the few via cloudflare those cookies get set too.
