The unfortunate wisdom in business is "nobody cares about privacy or security," and in my experience it's true. Outside a small number of people nobody even asks these questions.
With our own product ZeroTier we get maybe 1-2 questions a year about privacy and so far only a few enterprise customers have even asked about the security of encryption and authentication. "It's encrypted" is good enough for 99.9% of the market. Encrypted with what? A cereal box cipher? Nobody cares.
What do people care about? In my experience its ease of use, ease of use, ease of use, ease of use, and ease of use, in no particular order. An app that's a privacy and security dumpster fire but is very easy to set up and use will win hands down over a better engineered one that requires even one or two more steps to set up.
