employers and insurers will still use the info to deny people whenever and wherever they can.  People who can't fight back either because they don't know that's what was used to disqualify them from employment or gaining insurance, or people who simply do not have the financial means to fight it.

We all know there are a lot of questions it is illegal to ask a potential employee during an interview.  But years ago, while going through the hiring process at a very large company I won't name, I was asked for several personal references.  These I willingly gave, not knowing what I was letting my friends and family in for.

To a person they called me later, upset about the "interviews" that were conducted with them.  They were called, questioned about me in depth on topics that are illegal to ask.  Questions about my religious beliefs and habits, child-bearing plans, my husband, whether they had ever seen me have even a single alcoholic drink (I reckon that glass of wine at my wedding, which all these people attended, counts?), and many more.  It was insane and absolutely against the law.

Unfortunately my husband and I were too young, too poor and too unwilling to force our family and friends to possibly testify to pursue a case against them.  I still regret that we couldn't expose their hiring practices for what they were.

If that company could have gained access to genetic information on potential hires, do not think for a moment they would not have done it, used it, and lied about it.
