Dash directly funds the ability of devs to do this, I don't know how the distribution goes on Steem with this particular aspect.
Bitshares has also blockchain based funding for workers. I guess Dan considers it somewhat failure because it wasn't very effective. Opinions of what should be done were too diversified and not enough stuff got done.
I think the Bitshares' system is brilliant and the shareholders are the biggest problem. Too many people with too big stake who didn't share the vision that Dan had for Bitshares.
