Your service, on the other hand, operates in one of the Five Eyes countries by their own citizens. Thats risky to many. Further, it's a web service (easier to attack) with a ToS that's immunizes you from about any negative event. I did like the privacy policy but above things add up to plenty risk some competing solutions don't have.

Personally, I'd like to see a thorough look at existing and new providers to do a point-by-point analysis of such strengths and weaknesses of each. It's work worth a government grant or something.
