Unfortunately, it’s definitively an instance of intentional design. This whole consent dialog thing became a booming “consent management platform” industry. Many of them advertise better acceptance rates than the competition, or used to but have removed those claims in more recent times now that the big GDPR boom is over.

This particular dialog is TrustArc, who are infamous. At one point they defended it with a “well, we gotta retry if it fails to make sure your preference is expected, and we can’t know if your adblocker is causing it to fail or if it’s just a fluke”, which is one of those things where they say something that’s not totally wrong but you know they’re lying through their teeth.
