Rephrase it as "Which companies do you asses have the security practices necessary to adequately protect your health data?" and this makes sense.

Adding: To be fair, it probably more strongly correlates with "Which technology companies have you heard of?"

The fine print says this: n = 4000. This question was only asked to the 11% of total respondents who answered "Yes" to whether they'd share their health data with a tech company

So.. HN might be right , after all :-). Knowing nothing about how they chose their sample respondents, I doubt we can either agree or disagree!

This is quite shocking. :/

Google probably has it from reading your Gmail anyway if your provider emails you any information.
