That seems to be the advice of the UK ICO: https://ico.org.uk/for-organisations/guide-to-pecr/cookies-a...
Analytics cookies are not strictly necessary.
Alternatively your pagecount will shoot to the millions if you have someone holding f5.
These third parties will take what you give them and _also_ take what they can get from your browser if you're embedding their script. Are you going to proxy those scripts as well to stop them getting the user's IP address and then geolocating it to grab even more info?
The cookie warning banner is bullshit only in the sense that it achieves nothing. Accept it or deny it, it won't change a thing. Same with the tracking consent popups: despite the law saying they should be opt-in by default, they're still treated as opt-out by default, meaning that all of these sites _still_ collect your data because you're blacklisting individual sites from tracking, as opposed to whitelisting them. You need to set a cookie to say that you don't want tracking and not thousands of cookies to say you do want it?
That's being tracked... it's all wrong. Literally everything you offer as information, or don't offer, is another node in their graph.
WTF is that...
Completely at odds with the whole "informed consent" thing.
you'll need a cookie banner then
