This is super infuriating. I wish there was a way to offshore the effort and work needed to toggle each option off to the culprit website.
Perhaps when website A presents you with such hostile prompts, take their contact email, and subscribe it with automation to each of the vendors. I'm just too tired of this shit.
It's the second or third time I see this "managed by Google compliant with IAB" (note: not with GDPR)
