But enterprises may negotiate not to use (and pay) Copilot, can't they? Or go with another provider if it's such a big deal. Plus it being enabled by default in every VS Code (I haven't checked this, last I remember you need to sign in with GitHub) gets you on the free tier where you make zero revenue for Microsoft and some expense (not too much, probably).

No, no they can’t. Again, it’s a part of the agreement. It’s included and bundled with ANY service you order, like it or not.

So enterprises are just accepting paying twice as much as they used to for no value? The "c'mon man" should be directed at you!

No it’s just baked in. Not opt in. Just baked in.
