To me Amazon has been as they describe themselves an A to Z online store that sells everything. I could better understand if they themselves decided not to sell the devices, yet they are also banning third party sellers from selling them. This is a strange move, and I would be very concerned if I was a competitor who depended on AWS. This a petty move by Amazon. They are becoming a "Smother" with their services, from pushing Prime to locking in authors for Kindle Publishing. They are becoming the defacto online retailer of everything. Let's hope they don't develop a rough Amazon brand of toilet paper, would be too bad Angel Soft.
