Obnoxious banners are not required under GDPR. In fact, unless denying consent is as easy as granting it, they're illegal.

It's not the law's fault that companies would rather implement such detrimental UX than either give up the teat of personal data or give people their rights.

It is, however, the fault of regulators for not stamping down on such behaviour when it is against both the letter and spirit of the law.

And, honestly, I consider the fact that so many websites are forced to admit that they are trying to take and sell my data to be positive.
