I don't see X anymore - not just because of Elon but also in general all this social media is geared towards making people angry. Much better for my mood when I stay off all social media designed around highlighting outrage.
Back on topic - yes - its possible Elon asked his senior leaders to tweet more often.
ps : BTW, VP in one company is not the same as another. In MSFT a VP could have 1,000 people working for them. At another large company I was with, they could have just 5 junior programmers !
