> patients should get notified and paid every time someone uses an element of their data
I don't know about most people here, but I wouldn't say that. Notification or being paid is beside the point. The point is that informed consent should be obtained.
You're right that blanket consent forms don't count as "informed consent" for this sort of thing because they don't actually inform you.
> Personally, that seems like a bad tradeoff to me
Which is fair -- you'd have no problem giving such consent. I, however, would not be willing to give such consent.
I put a lot of effort into reducing the amount of data that Google (and Facebook, Amazon, etc.) can get about me. If/when my medical provider just hands my data over to them, that's a very serious betrayal of trust and undermines my ability to protect myself from those companies.
I find that completely unacceptable, particularly because medical care is not exactly an optional thing.
