That was a hard bridge for me to cross for a long time; I got there via sustained in-depth conversations with folks there who simply wouldn't stand for something that breathtakingly opposed to everything AWS has strived to achieve from a trust perspective, that they'd sooner tear it all down than implement such a thing.

Some folks can't get there, and that's okay; if you don't have that level of trust, perhaps the cloud is not a fit for all of your workloads.
