Question is, if this has always been the case or has become a new/increasing phenomena. I would call foul if insurances could just weasle their way out of anything that might affect their bottomline because they miscalculated risk. What if your life insurance drops you because they suddenly get access to genetic data, so they increase their odds after the fact?
