Fully aware AWS and amazon are different, but my point still stands IMO. Not sure why some people have so much trust in massive corporations who utlimately are all about making money for shareholders. For some people it's like supporting a sports team. My trust in them is one of caution and low expectations.
I said that because I worked at AWS, because I have seen the internal processes in action, and because I am aware that AWS has far more to lose by looking at customer data than they can gain.
Understand that as well, but its not always enough of a deterrent for some companies. And things change. Caution is a good thing IMO, e.g. don't lock yourself in so you're always capable of moving your solutions.
