I think it would be inaccurate to say you can't learn things from telemetry. You can easily run A/B tests, or even in the absence of proper A/B tests, you can see if a newly added feature is actually being used or not. The other thing one is the timing of action - I bet you could learn a lot from that, especially if you take a nice group of people, watch and quiz them, line up your learnings with the telemetry, and then use the telemetry of your general user base to infer how your user base is responding. Standard flame-war prevention disclaimer: I'm not saying we should add telemetry to everything. I'm just saying it seems like it could be another useful tool in product creation.
