Wouldn't that be illegal though?

Purely from a Devils Advocate perspective those banners are legally required, so pro-actively blocking them seems like a bad idea.

I think the cookie consent was great in intention, but naively executed/enforced by the EU.

I believe there must be a strong push back on those banners from browser vendors to force the EU to reconsider the current law and modify it. IMHO it would be much better if they'd revise the current law to require browser vendors to have a global cookie setting (accept functional, marketing, etc.) and then websites having to obey to a user's preference based on their browser setting.

There used be the option of using a global cookie but website no used it. It was then deprecated. See the field 'IsServiceSpecific' in [0]
