The difference between invasive and non-invasive telemetry is choice. If you give me the choice to turn it off, there's some sense of mutual trust: you trust me to leave it enabled if I have no reason not to and I trust you not to abuse the information collected. When there is no choice, as with Windows 10, I have to wonder why. What are you collecting that you won't allow me to turn it off at my discretion? What are you doing with that information that earning my trust is not an option?
