Note how nobody has said how.
Well, I imagine rm -rf libtelemetry.so would do the trick
Seriously, though, it's pretty clear that Clear Linux is designed for server deploys, in situations where I'd guess the telemetry service might catch issues in order to make an admin's task easier. It's touted by Intel as a feature of the distro, after all, so they obviously think some people will find it useful. They also note that the telemetry service is open source, so I imagine you could vet the code if really wanted to.
Would I want a telemetry service running on my linux box? Hell, no! But I'm also not the target market for this distro.
