My unpopular opinion: they shouldn't seek consent, this should be completely opt in. Draconian laws should make this happen and flip this backward industry so everything is opposite.
“Asking for consent” doesnt automatically mean a pop up. “Asking for consent” isn’t even a technical term. It just means that personal needs to give permission. Exactly like an opt-in option does.
Moreover, popup is still technically a form of “opt-in”. “Opt-in” doesn’t mean the option is hidden. In fact plenty of sites use dark patterns to trick people into opting in.
In that case I don't think this would be an unpopular opinion - I can't think of anyone who would rather have a pop up thrown at you than having adverse side effects (tracking) hidden in some obscure setting you never see.
