Yeah, this is the only thing that makes sense to me. I'm assuming somehow she thought she was about to be on the hook for something and is ejecting with public notice to avoid the fallout.

However, I'm also more than a little concerned about her legal judgement. I really can't see how blocking employees in certain countries is illegal--especially for China and Russia. Country of residence is not a protected class, but China and Russia, specifically, have sanctions of various levels applied against them.
