I’ll happily allow telemetry if its an open source piece of software that gives you the option to “preview” what is being sent (and preferably, not automatically, but as a “Here is what we’ve got, does this look good?” thing). I’ll have a look, make sure its nothing confidential, and send it.

Steam does this with their hardware survey, Fedora does it with its crash reporter system (as did Ubuntu when I used it long ago), and actually macOS was usually pretty good about this too from what I remember (though macOS of course isn’t open source).
