Why it's weird to blame them for product names? Because their purpose slightly different. I can see where negativity comes from and understand, but product name is a lot less important as consistent API experience. AWS is the best among big players by far, hats off and well-done to their teams and leadership. I hope the others will finally learn and follow.
My issue isn't just with the names themselves but they are emblematic of AWS's overall mentality. They want to have the AWS(TM) solution to X business case while other cloud providers feel more like utilities that give you building blocks. This obviously works for them and many of their customers I just personally don't care for it. It is probably to do with the level of complexity I am working at (*which is not very complex).
Also, I don't think trying to emulate AWS's support and consistent API makes sense as a strategy for other cloud providers. They will never beat AWS at their own game, it is light years ahead. If cloud providers want to survive they need to fill a different niche and try different things.
