The only straightforward thing about this law is how ignorant were its creators.

The cost of implementing it was in the billions. The human time cost paid for all those damn cookie popups we keep having to click on is probably already in the thousands of life-times wasted, and it keeps on growing.

No it's required for all types of tracking including but not exclusively cookies. Only days collection that is absolutely required to provide the service may be collected without consent and for that purpose only.

There's the law, you complain that it's badly written, that it's impossible to understand, that it's impossible to implement. Even though it has multiple recitals to explain things. Because you've never read it and never tried to understand it.

There are multiple guides and explanations for the law. You complain that those are not official.

One thing is definitely clear: 6 years later it's not a problem with the law. It's the problem with you and other people like you who diss GDPR without taking a single step to understand it.
