The Data Collection section needs clarifications

> The software may collect information about you and your use of the software and send it to Microsoft. Microsoft may use this information to provide services and improve our products and services. You may turn off the telemetry as described in the repository. There are also some features in the software that may enable you and Microsoft to collect data from users of your applications.

This section should be improved:
* It is not clear what exact data Microsoft gathers and for what exact purpose the data points are gathered.
* While it does say that you can disable telemetry, the text just points to the repository in general. The documentation is long and it is not even clear if the instructions are in the README or elsewhere in the repository.
* There is a `disableTelemetry` option, but it's not clarified if this applies to all telemetry or to the telemetry intended for Microsoft purposes.

Lastly, it would be fantastic if the telemetry sent to MS would be opt-in, rather than opt-out.

Start by locating the Data Collection section and the `disableTelemetry` option in the repository documentation and implementation. Determine what telemetry data and purposes are documented, where the disabling instructions belong, and whether the option covers Microsoft telemetry; done means the documentation answers these points and clearly states the opt-in or opt-out behavior.
