> once you voluntarily give your data to a third party-- e.g. when you sent it to OpenAI-- it's not yours anymore and you have no reasonable expectation of privacy about it.
The 3rd party doctrine is worse than that - the data you gave is not only not yours anymore, it is not theirs either, but the governments. They're forced to act as a government informant, without any warrant requirements. They can say "we will do our very best to keep your data confidential", and contractually bind themselves to do so, but hilariously, in the Supreme Court's wise and knowledgeable legal view, this does not create an "expectation of privacy", despite whatever vaults and encryption and careful employee vetting and armed guards standing between your data and unauthorized parties.
I don't think it is accurate to say that the data becomes the government's or they have to act as an informant (I think that implies a bit more of an active requirement than responding to a subpoena), but I agree with the gist.
