+   - Telemetry is essential: an e-mail client is a (_very_) large complex beast costing millions to maintain
+   - Opt-in telemetry _does not_ work and results in data that is unrepresentative and may be misleading

+   - Every new profile on first use provides data collection/use policy and the ability to opt-out
+   - It can be disabled at any time (Settings > Privacy & Security > Data Collection and Use)
