If nothing else, it definitely raised the awareness. The thing with cookies and tracking is that it's invisible. Especially for the average Joe users. But even I was surprised when, thanks partly to these dark patterns and not letting me to opt out with a single click, I saw how many trackers some sites actually use.

Now as users got pissed off, solutions started to emerge. Yes, the EU does not seem to enforce it too much, though I'm curious how many reports they get. Anyway, Mozilla just announced that they started compartmentalizing most cookies, so tracking will stop working for a lot of sites/services.
