I imagine the bulk of your data is collected when you show up for the blood draw. You have a really nice site, but should defiantly try to find and work with a more ethical and trustworthy lab. On the plus side, when they sold your data they probably had a lot of nice things to say about your intelligence, abilities, and aptitudes!
Quest is one of the two major testing companies in the US. (And LabCorp is not much better.)
I understand the sentiment here, but it's like saying "you should definitely try and find and work with a more ethical political party than the [reader's choice: Democrats|Republicans]". Good luck! It's not likely to happen, even if we all wish otherwise.
It looks like those two companies have been buying up competitors left and right for a long time, so no wonder there aren't many other options left out there. Seems like this is an industry that doesn't get a lot of attention, but which is badly in need of oversight and regulation.
