It seems more likely that, for unexplained reasons, she was not in the loop on the area she was employed to work on (Global Compliance) and decided therefore to resign. She may have reasoned that this type of policy would have made working in BRICS countries very difficult. Ironically, these countries routinely impose residency and nationality requirements, local hosting and censorship etc.

The lack of nuance in her public communication is quite strange for a lawyer. 'Retaliatory behavior' -- against whom are they retaliating and for what? A serious allegation. And other strange and strongly worded warnings of illegality, but which have no basis in law that I can see. So, bluster? Trying to win an argument?

I can't help but think that remote work is not for everybody, and especially not for lawyers.
