Consent not freely given is not consent w.r.t. GDPR, so legally I'm not sure what the point is other than baiting the data protection agencies. So just because you agree doesn't mean it's binding, especially if it's unlawful. E.g. in Germany, contracts presented after purchase are void (EULAs), and you can't sign away your "Urheberrecht", or author's rights - which has interesting implications for copyright licenses. However, the regulators will take a very dim view on such behaviour. I don't know what they're trying to accomplish.
