I've seen in a few places cookie popups that have their 'accept' button with text along the lines of 'don't care' or 'whatever' etc... was just wondering if there might be any legal implications for this.
I guess that would depend on if there was a legal requirement in your jurisdiction to have such notices.
It typically depends on the location of the individual.
Yes there is a legal basis, it's GDPR. Unless you block all Traffic from EU.
