Palantir's an utterly terrifying US spy tech company - which recently bought control of NHS England's data for half a billion quid.

Protection of my medical records is one of the things I have major concerns about (and do what I can but it's a challenge).
I'm happy for NHS to use my record for analysis of service provision, etc. (ie not directly related to my treatment). I'm happy for academic researchers to have my medical records for academic public funded research where results are put in the public domain.
What I'm not happy about is where my records are use by "for profit" corporations where the research results are used to develop the profits.
I have taken part in several clinical trials, mostly long term studies and I've given some access to my full medical records. But I've also withdrawn from some where the body holding the records has proven "unreliable" in passing data to 3rd parties contrary to their undertakings.
