When I said internal matters, I did not have any specific information in mind, just internal company matters. If engineer #34529, profiled liked to SpaceY says on Twitter that his group has lots of overtime. He could be fired in a case B situation. And yes, information like that could be coupled with other information to figure out what projects the company is working on. It is my belief that confidentiality agreements and NDAs, along with non-compete clauses are overbroad and expand beyond what companies are allowed to ask of their employees.
