How can the ability to transfer data to another cloud provider or your own server increase price?? Doesn't that mean there is more & fairer competition?
I think they mean that AWS et al will make that margin up somewhere else by either charging for something they didn’t charge for before or increasing prices.
Companies don’t like to have their bottom line affected.
But the real key to Amazon wanting to charge high egres fees was to keep you from moving your data out. If they raise prices elsewhere, there is one less barrier to moving to one of their many competitors.
