However it was revealed not long ago that a lot of the third party cookie consent forms used by the majority of sites don't actually have any effect when you interact with them... i.e they tracked everything whether you consented to it or not, I think it was a combination of negligence (incomplete software) and betting on the fact that the vast majority of people just hit accept due to dark patterns that make it extremely inconvenient to do otherwise.

I think using uBlock etc is more likely to result in preventing tracking through blocking known urls and code etc compared to hiding consent forms... I know it's far from infallible but currently most trackers don't bother going to extremes if you block them.

i've found a good few websites break when you don't interact with the cookies banner that IDCAC removed.
