Clear ad-hominem attack if I've ever seen one. Maybe the comment could have been better phrased as a question: What is actually unprofessional about Amazon contracting package delivery to random individuals? I'm not in favor of it, but I haven't thought about it enough to have a good argument about the topic. @viperscape does bring up good points though: personal vehicles and the perception that Amazon has "granted permission" to random people to enter property and handle their goods. What are the arguments in favor or Amazon's new delivery model?
