People are too critical of founders for either selling or not selling stock...they can't win!
@JeffBezos is criticized for "not paying taxes" if he doesn't sell $AMZN shares, and then he's criticized for selling shares, despite selling just 2% of his shares (~$4 Billion), which will trigger ~$1 Billion in taxes.
Plus he's likely going to invest most of the proceeds in more awesome companies, like Blue Origin.
And btw, in Jeff Bezos' case, he never had a real pay package at Amazon. His salary at Amazon was $81,400 with NO STOCK, NO BONUSES and nothing else! He declined extra pay because he already owned a massive equity stake in Amazon and felt he did not need further financial incentives. (unlike another founder who shall remain nameless)
