"Telemetry" is not "sending the contents of your documents" (or at least, not necessarily so). This comment kind of demonstrates my point about the complete lack of nuance in these conversations.
And to reply to your reply:
> That’s exactly what telemetry is
The common understanding of telemetry is sending metadata about how people are using software. That is, things like "this button was clicked", "this feature was used", etc. That is my understanding of the word anyway.
Either way, this is a bit of a boring semantic discussion; my point is just that there is nuance to these things, and that this article doesn't really tell us anything concrete beyond "the network is used". Well, okay ... but for what, exactly? Because that does matter.
