Trust is not the issue. Google wants to sell "management" while AWS (et al) are selling raw resources. To use Google Cloud you have to change or build your system for it, using new APIs, configuration systems, other managed services and even programming languages. Todays announcement was: you can have raw VM control with our management too! I don't see it being any easier now (even MORE options!) but I think they're on the right track. They need to make it simpler rather than cheaper.
