The point I think you could be missing is that the organizations which do this have been at best irresponsible, at worst negligent, in protecting customers personal information. There are obviously benefits to ~~this~~ a genetic record. Preserving a comprehensive genetic record for future generations to study is one. A database for law enforcement to use to solve very serious crimes like murder and rape. All that would be wonderful, but that information is already being misused and abused. Most people, myself included, don't think these organizations will ever be responsible to their customers cause who the hell would believe that these days?
