>You can’t preemptively fire someone for something they haven’t done nor even attempted/planned to do.

You can fire someone for no reason at all in much of the US. It's employment-at-will.

Which is crazy. But just because you can fire someone for no reason doesn't mean you can fire them for illegal reasons, which appears to be the case here.

Within reason. Firing for revealing your salary, a protected action, can get the employer in trouble even in at-will states.

True, definitely depends on where you live although I also meant that in a more broad 'moral' sense. As in, giving the reason that they /may/ release 'secretive' information without any indication that it would actually occur is ridiculous to me.
