It's always both, the people willing to pay someone to make things worse, and the people willing to take the money to do it.

I mean I agree, I'm against advertisers.

But advertisers exist and will continue to exist, and have no incentive to follow this. I don't think either are at fault necessarily; I think it was a weak attempt all around.

The only thing that will get companies to comply are a/ laws (and so far all laws have done is annoy end users) b/ browsers doing more to block tracking (which is almost impossible; this will forever be a game of cat-and-mouse).
