You're assuming everyone agrees on "need". People disagree with governments all the time, so it's not surprising here that a website operator might consider a cookie to be necessary for the operation if their service, but the government views their needs differently?

If i can delete the cookie and nothing goes visibly wrong, it's obviously not needed.

Same with blocking a script that sets such a cookie. Most cookies are not needed for providing a service.

I think they literally mean "technically need". This is objectively deductible.
