That’s obviously not what enabled means, at all.

If there is a button visible that executes a function when receiving a click, that feature is enabled.
That does not mean that the feature is actively in use, of course. Enabled and active are different states for a program’s functionality to be.

I believe it’s pretty easy to understand, there are people like me who don’t want to have AI functions popping up in our browsers without explicit enabling on our part.
I understand that you disagree, but it is not a difficult position to understand.

You don’t need to re-define opt-in and opt-out just because you support Mozilla in adding AI features to Firefox.
