Respect the users: let them tell you what they want, when they want, and how they want. To expand on this a bit, the past several years advertisers and attention brokers have focused on the difference between stated preferences and observed behavior, optimizing for the latter. Unfortunately it seems optimizing for observed behavior amplifies the worst of our base instincts, so even if it improves the bottom line in the short term, we are degrading our civilization in the process. It's possible a similar discrepancy between behavior and intention exists in UI telemetry. Ask people what they want when at their best, don't optimize for measurements of them at their worst.
