Companies have existed for centuries without needing constant telemetry... we have many methods that do not require telemetry: surveys, emails, forums etc.
In fact, there is a subreddit here [0] that the devs/owners could easily ask questions.

Edit: Also, I think people are totally jaded with telemetry. There are some companies that take data whether you want them to or not so people are naturally wary... what's to stop them pushing out an update that grabs a massive pile of sensitive data and then when the backlash starts, they throw their hands up and say "sorry"... much like Google do/have done.
