How ironic, websites have been breaking user experience for years by embedding always more trackers that took forever to load. If a publisher doesn't want to display a GDPR notification to its users there's a simple trick : just don't collect and monetize personal informations!
Even if we use cookies for basic sessions (absolutely no personal tracking, just session ID) - Isn't it mandatory to show "Cookie bar" on the said site?

(Perhaps surprisingly there is an exemption for "third‑party social plug‑in content‑sharing cookies, for logged‑in members of a social network.")
