You seem to have a problem understanding the concept of consent.

Allow me to help you. You ask first. If the answer is no, you don't do it. If you cannot master this skill, or refuse to, you are embarking on becoming one of the most problematic demographics on Earth.

There is no excuse for not asking, and honoring the answer. Sending data is not free, and I guarantee your telemetry is not that important, neither is your vaunted sampling. All you want is to know who your Users are, and the fact is, that is fundamentally gated behind them wanting to even bother telling you.
