I'm saying as someone who works in software I empathize with the idea of spending lots of time implementing a feature, tearing hair out over some technical issue, etc. only to realize no one uses that feature.

I'd rather people be able to opt-in, but conceptually I'm not really upset that people can see my usage patterns, etc.

I think most of us work in software. Asking for consent isn't hard.

Telemetry won't tell you nobody wants a feature you haven't implemented yet. User research might.
