It is not allowed in the EU to gather data without informing the user and (in some cases) requiring opt-in. I think this is a very sane decision, even if it makes developers uncomfortable, because it is a privacy issue.<p>It is not usual to gather telemetry on the desktop, with perhaps the exception of some AppStore apps. Of course now that Microsoft got greedy and web developers are starting to develop desktop apps, we might see a different trend.
