My primitive reading of libertarian philosophy in this case would go something along the lines of: Companies should lobby for whatever regulation/deregulation benefits them because they are rational actors in a free market. However the government should not have the power to actually grant this. I suppose a hardcore libertarian might allow a contract clause which allows the phone network to hire someone to shoot you in the face if you unlock your phone.
