Bill doesn't have to answer a single question. CEOs are not required to answer questions via social media. He does so because he is an exceptional individual.

This board does not influence his business decisions. The future of this company is completely in his very capable hands. There are well intentioned people on this board, but being influenced by anything posted here would be the worst thing that Bill could do.

The hard fact here is that you have to either trust that Bill will do the right thing or sell.
