You don't get the point. There is no problem to spend the coins to support their development. But spending coins all the way out doesn't seems like they are interested in that project at all. Steem literally fell to pennies from 4$. If they really value their project. They wouldn't dump the coins if the market fell below a dollar. And it is definitely not better.

If they wanted to support themselves, they could have reduced the liquidity and made the same amount they required.

1000 Steem @ 4$ = 100000 STEEM @ 0.04$ both are same. And strangely they chosen the second option. Because the second would not help anybody else and the first would have helped others to spend.
