Two issues with this:

1- Vulnerabilities, Secrets can be leaked to other users. 2- Intellectual Property, can also be leaked to other users.

Most smart clients won't opt-out, they will just cut usage entirely.

That's me. Frankly, looking at just uninstalling VSCode because Copilot straight-up gets in the way of so much, and they stopped even bothering with features that are not related to it (with one exception of native browser in v112, which, admittedly, is great)
