Fingerprinting is just an implementation, banning it will just drive these companies to invent new tricks. That's why the GDPR doesn't specify any technical tracking methods, whether you're using cookies or fingerprinting or a camera drone looking at the user's screen, tracking without consent or good reason is banned.

I doubt politicians care much about fingerprinting, though. They're more afraid of actual businesses getting attacked by bots than they are about Linux users with weird setups not being able to access some websites.
