Going batshit with browser APIs is also a formidable GDPR defense. e.g. try browsing the privacy-related forms for Google (https://myaccount.google.com) on Firefox :D (entire browser freezes up every other second for me, because of some extremely important work Google needs to run on my CPU to let me scroll down on a static site containing roughly 30 words)
Yes. In this case probably not fineeprinting is not allowed because not strictly necessary (cookie law) and therefore needs consent from user.
