I appreciate your bringing up that site guideline above, but here you're crossing into personal attack. Please don't do that.

OP shouldn't have to use private browsing, that's the entire point of the regulation, and that does not prevent cookies from being used during a session anyway.

What neferious use is of a cookie when it's only used on one page?

Potential behavioral fingerprinting via cross-analysis of sessions. The more important point is that OP should not have to change their habits if a company is maliciously complying with regulation; the regulation should be tightened.

Isn't that going to happen regardless of cookie preferences, because the whole point of fingerprinting is to avoid cookies?

That doesn't mean we should throw surveillants free bones.
