If you're in the US then the tech giants can already easily get your de-identified billing data. Billing data would contain what was done, by whom, when (probably only at a year level), where and why. It costs money but a drop in the bucket for them. So the question is I feel, given that this has already been done, has this caused real-life problems for anyone? Known re-identification would be a HIPAA violation I believe so more likely to be reported.
