> Why would a company ever want to release any product without strong encryption (end-to-end) when users never complain about their data being encrypted. The only reason companies don't encrypt is when they have a vested interest in spying...

I think the second thought doesn't follow from the thought before it. to my experience, the main reason companies don't encrypt is because it's simply makes it that much harder to debug problems and consistently provide successful connections for users. HTTPS can fail in ways that HTTP does not.

If users aren't clamoring for encryption as a feature, the main reason not to provide it is simplicity and quality of service along the axis users appear to care about. If users want encryption enough that they're willing to tolerate that sometimes browser misconfiguration or server side error will cause the connection to fail because it cannot be trusted, then companies will implement it.
