"No, no, but GDPR bad!!11 We care about your privacy that's why we collect all the data we can, sell it to everybody and store your passwords in plaintext" As said by several ad-supported businesses and especially ad-networks.
99% of critizism against GDPR I've seen is either about how it's poorlt implemented (but still a good idea in principle) or about cookie banners (which are note ven GDPRs fault though); I don't think I've ever seen anybody complain that the whole concept of GDPR is bad.
