I don't understand the EULA part. Are you saying that if a company sells eyeglasses with 24/7 audio and video recording to an microSD card, then that company would have an interest in adding a EULA that prevents using their own devices in a court case against someone else? Or are you saying that a hospital would have an EULA that prevents one from using any recording one might coincidentally hold of interactions with them in a court case?
The company won't be selling a 24/7 microSD recorder, it'll be selling a 24/7 cloud recorder, for the usual bullshit reasons that are ostensibly about convenience, but in reality are about securing recurring revenue. Since you won't be using a product but a service, there will be an EULA, and the company may not want their data (at this point it isn't your data anymore) trawled in random court cases.
Might not, but EULA may stipulate that breaking it will cause termination of account and deletion of your data. It would be similar to forced arbitration clause, as far as I understand them - i.e. it's not that you can't sue the company, it's that you'd better not, if you want to retain your account.
That's good for the other places (and I'm happy to live in one), but here we're talking strictly about the United States, as the article pertains to US federal government matters.
