Q&A How do I firewall all telemetry?

How can I block all network requests that look like telemetry at the network level? I realize that "looks like telemetry" is a nebulous definition - it would probably involve a lot of custom logic...

I realize that "looks like telemetry" is a nebulous definition - it would probably involve a lot of custom logic. I am willing to maintain my own rulesets, so long as I have a generic starting point. I don't want to catalog all the telemetry signatures unless there's a very convenient way to do it.

A system like this would always have some false positives/negatives, so there should be a convenient way to add both temporary and permanent exceptions as needed.

-------

I don't want to hunt down the telemetry setting of each program I use individually, turn it off, and hope it works.
