I think that doesn't weight as much in people's opinion because the counterfeit problem only came uo in the last couple years. AWS hat already a good reputation by then.
Yep. Amazon search has built that trust of Amazon (although plenty of retail companies refuse to use AWS because of the retail competition). But there was a time when Google was universally the coolest company in the room - and I'd be interested to see how deep the trust well goes with amazon. The one thing with amazon you can trust is that they want to make money, and cloud makes them money, so they're at least not gonna pull the plug on you.
