It was awesome when Facebook deleted NSO group employees personal profiles. And then they whined about it. The silver lining of Facebook owning WhatsApp. I hope more organizations do this. https://arstechnica.com/information-technology/2019/10/faceb...
They didn't just whine, they sued Facebook in Israeli court (and won). Facebook was forced to reinstate their accounts: https://www.cyberscoop.com/facebook-nso-group-accounts-reins...
Facebook will probably have better luck with lawsuits in the US.
