Perhaps you have other stuff on AWS, in a VPC, that is administered by an operations team which is several tickets away from you and/or you have to talk with seven layers of management before you convince anybody that a VPN peering with a cloud provider may be cheaper than the hours you just wasted with expensive meetings just used to discuss the possibility of setting up a VPN peering let alone actually executing it and maintaining it...

Yeah, many companies will gladly pay an inflated per instance price as long as every else flows smoothly
