My objection is not really that they hired him. I believe that people can change and no one is irredeemable, but I don't think they should advertise it like this. It's like hiring an ex-con who used to use your product to victimize others and then bragging about it and getting upset when people are unconformable with it.
If nothing else, I think they should show more respect for people who are victims of the police and state-sponsored surveillance.
