Just FYI, sentry is error capturing and reporting tool, not "telemetry". It could be potentially abused to collect "telemetry", but there are far better tools for that so it'd make little sense IMHO. I've used it extensively for error management in a previous job and it worked very well, correlating with env, release, etc. and it was great ( it was the self-hosted version, but still). Not affiliated in any way, just a happy "customer" ( never paid so not really a customer).
As a user of sentry technically, you're also aware of how difficult it is to keep user information out of those errors and stacktraces. Just paths are enough to start leaking information about you and your system that just shouldn't leak from your terminal to the internet.
