You might be right to some extend, but not entirely. For example, there have been almost no incidents in AWS where one customer would be able to access the data of another customer because of AWS fault. The cases so far like Superglue etc. were very limited and IMHO AWS security is quite solid.

So I would say there is a difference between AWS architects and engineers (although I know first hand that certain things are subobtimal, but...) and those of several other companies who have less customers but experienced successful attacks (or data loss). Even if you take Microsoft, there is huge difference in security posture between AWS and Azure (and I say this as a big fan of the so-called "private cloud" (previously know as just your own infra)).
