That said, if you want Mozilla (or other organisations, for that matter) to make decisions based on how you're using their products, then it doesn't seem like an unreasonable expectation from their side that you tell them about that usage, i.e. through telemetry.
At the same time, people disable telemetry because as we've come to understand much more clearly as a society (and some of us already knew long before "recently"), there is too much data floating around about us as it is. Not all of it stored in a secured, anonymized fashion even if the organization in question claims to. People are skeptical of automatic telemetry data collection for good reason.
It's more them asking specific questions for preexisting objectives - and my browser answering them, often without me even knowing the questions.
From where I'm standing, your comment is straight out of Kafka. You just apologetically ("I'm afraid") keep insisting that the hostility being experienced is "the best way to deal with this."
What is your source for the proposition that Firefox gains from removing RSS?
What is your source for the proposition that telemetry is superior to randomized user surveys?
