You're right, I have no idea what I'm talking about, clearly people aren't going to leave and follow Sam instead of Ilya. Nobody at all... just 550 of 700 employees, nothing to see here.
Including Ilya Sutskever who is (according to the posted document) among the 550 undersigned to that document.
It's pretty clear this is a fast-moving situation, and we've only been able to speculate about motivations, allegiances, and what's really going on behind the scenes.
