...but your post reads like you do have an emotional reaction to this question and you're ready to believe someone who shares your views.
There's not nearly enough in here to make a judgment about things like security or privacy. They have the bare minimum encryption enabled. That's better than nothing. But how is key access handled? Can they recover your email if the entire cluster goes down? If so, then someone has access to the encryption keys. If not, then how do they meet reliability guarantees?
Three letter agencies and cyber spies like to own switches and firewalls with zero days. What hardware are they using, and how do they mitigate against backdoors? If you really cared about this you would have to roll your own networking hardware down to the chips. Some companies do this, but you need to have a whole lot of servers to make it economical.
It's really about trade-offs. I think the big trade-offs favoring staying off cloud are cost (in some applications), distrust of the cloud providers,and avoiding the US Government.
The last two are arguably judgment calls that have some inherent emotional content. The first is calculable in principle, but people may not be using the same metrics. For example if you don't care that much about security breaches or you don't have to provide top tier reliability, then you can save a ton of money. But if you do have to provide those guarantees, it would be hard to beat Cloud prices.
