Re: Oath Hell too please ... and worse
"I'm not sure how they would store your preference if they can't store cookies or include any sort of personal identifier."
If you don't have a cookie, e.g. because you block or delete cookies to prevent tracking, and for that reason they cannot link you to any record of consent, then the default assumption should be that you have not consented. To do what Oath, Facebook, Google et al do, and assume you have consented by default, and then require you to jump through hoops, and enable tracking in order to "withdraw" this "consent" that was never given is hardly in the spirit of what is meant by "freely given consent". And in some cases you are not even given an opportunity to withdraw consent for some non-essential-but-profitable uses of your data. Of course changing the defaults to make them comply with the law may have implications for some business models, but that is hardly news
Other US-centric companies operating in the EU seem to have been very poorly advised, even when compliance should be trivial. Some have "opt-ins" for non-essential sharing with third-parties being written into new, supposedly "GDPR-compliant" contracts, which have to be "agreed" to in order to continue using a service, and terms concerning jurisdiction that seem intended to prevent prosecution under GDPR legislation, despite having a physical presence in the EU. This would have been dodgy even under the pre-GDPR regime.
I'm having to deal with one hosting company that has required me to accept a new contract with terms that allow sharing of personal data with third-party marketing organisations, and "Modal Contract Clauses", in order to continue using an existing UK-based service. The only nod in the general direction of "freely given consent" in this case consists of the opportunity to write to their head office requesting that they do not share personal data with third-party marketing companies. And this for a company for whom GDPR compliance is actually in their interests if they want EU companies to continue using their EU-based hosting services without themselves falling foul of the regulations.
