Yeah that's legitimate. "Amazon doesn't care enough to make sure counterfeits are struck down, continuing to put people at risk. Why wouldn't that corporate culture and lack of concern for the well being of the customer transfer over to AWS? What if I'm hosting with someone that'll leave big security holes or oversell capabilities just to drive sales at the expense of quality?"
Trust is trust, and if amazon can't be trusted to behave well in one context, over time, that erodes people's trust in the platform to behave well in other contexts. Thats what's going on with Google - they killed reader, and it's the same company, why are we magically expecting different behavior in cloud?
It might not be warranted, but that's irrelevant. Trust is earned, and Google isn't entitled to it, they have to earn it. Doesn't matter how they lost it, market forces are market forces, they need to get it back
