I think his focus is, to manage his fund and his position in the company with appropriate diligence and in a manner that won't even create a hint of divided loyalty, disloyalty or a conflict of interest with the investors interests to whom he owes a fiduciary duty.
I think the nonsense on the boards about his not investing more or needing to invest is based on no real information, is purely speculative, and is mostly, without much basis or merit. But that's just me.
I do think, that he held his investment, is about as good a sign as one can get, in this context, plus his positive statements about his continued belief in the technology. That's about as good as one can get from any investment manager, generally speaking.
So I think, whenever this is discussed, even when speculating that he is about to take action he may not take, it can result in very negative outcomes because people then have to look at potential actions, instead of focusing on his consistency and what he has said and done, and not done, already.
