My copy of Audacity hasn't auto-updated to include any of that crap and it looks like future updates will come from a fork where it's stripped (if muse group even bothers to continue) so I'd say that's an example of it working.

Unless you were unaware of what was happening with Audacity. If you didn't hear about the news, you'll update and have no idea.

I installed it from guix, the package maintainers are aware of the issue and will not distribute updates containing telemetry.

On Debian, updating won't add unwanted internet connectivity.
