I think that sets a dangerous precedent. If companies are unwilling to make games unless their paid for in advance, but still happy to pocket the profits of said game after the fact, that puts a huge burden on consumers that wasn't there before. It ceases to be a "democratization" at that point.
Publishers will never be "unwilling to make games unless they are paid in advance" because their business is releasing games to make money from it. If they put up Kickstarters for everything, and half of them fail, and they decide to just sit on their hands and not make anything, they will go out of business. So there's really no concern there. There is no "dangerous precedent".
