Yeah, but if you're not aware of this gotcha, the extension takes the choice away from you. It's good that the parent post highlighted this issue.

I don't care a lot about cookies, but if a website is abusive enough that they need to ask for my permission, I prefer to deny it rather than give them a blanket approval (again: what I really care about is wasteful and overbearing JavaScript code that complements tracking via cookie... If I cannot object to that, at least let me object to cookies used for tracking)

Again: you don't need permission for necessary cookies. The fact that the cookie prompt is annoying/difficult to parse and requires opt-out instead of opt-in is against the spirit (and possibly the letter) of the law. If our automation around the cookie prompt is accidentally giving an implicit consent, we ended up doing exactly what the people that push pervasive tracking wanted. We end up rewarding, instead of punishing, people who implemented dark patterns.
