There has been and there is still a lot of self-checking at Google...
The own health data of Google employees too is in danger if they do dumb things with it (as I suspect that, like anybody, these engineers enjoy health wearables), so it would absolutely not stay unchecked.

The DNA-box companies sell randomized data to drug companies, to help literally make cures for disease. Not do bad. And it's random, and there's buy in.
I can see G people going for that: it's random data from Android devices, people are opting in etc..
I understand the risk, but I just feel that everybody is fretting while overestimating this risk and overlooking everything that already exists that can also very well keep this risk in check. Starting by the fact that any misdeed would be soon made public and widely commented, like always.
