I assumed she was paid out her 2 weeks. Do you have reason to believe the didn't or won't do that?
I think the wishing of luck was circumvented by the media firestorm. Her first tweet was about losing corporate access which is usually the first thing H.R. does once a decision has been made.
She shared what she claimed was an email from her manager. It said her employment was terminated immediately because of her email to non management employees. I believe it was sent before the first tweet. She shared it before the media picked it up.
The employee remains employed in your scenario. Just without duties or access. Terminating employment immediately and not saying anything about severance implies not paying.
