It's a balancing act. We built it, to build trust. But talking about it too much would - we thought - highlight concerns and increase worries that we hoped (most) users wouldn't have.

As an example, we were very clear and upfront in the original product detail page that users' voices went to the cloud, as we were not trying to hide that. Even so, some people tried to play a bit of "gotcha" and fear-mongering about the fact, as though we were not being transparent.
