Earlier quoted context omitted.
Nat is a mogul in SV. Everyone knows him, many even before GitHub. Simply walking away from GitHub without much of a speech would make it seem like he didn't care or left on bad terms, optics-wise. That would have a potentially serious effect on perception and thus shareholders would be affected. This clearly isn't his intent. I offer a contrary point of view: why does it bother you so much? Simply do not read it.
>thus shareholders would be affected Why not just tell it like it is then? Dear shareholders, I'm leaving because I'm rich / bored with Github and not because there was a falling-out. >why does it bother you so much? Simply do not read it. So you're suggesting people should just not read or listen to anything that they don't like? And just keep quiet?
This case has more than 50% likelihood.
