When you have a truly compliant gdpr dialog, aka simple yes/no, I found lots of non tech people around me click no. I'd say about 50%
This should make it a lot easier :) It auto-handles most gdpr permission walls, and yes, you can set it to reject all - that's what I do!
(I'm sure this exists for Chrome, too, but if you care about this sort of thing you really should be using Firefox!)
People care about this, so no wonders the industry as a whole is up in arms about it.
