Thankfully, that's not even what's happening here. If you buy the first half of the game on Steam, you get the second half when it's finished at no additional cost.

Talking about asking for more money isn't exactly right. They aren't, really. They are selling the game to people who aren't backers. If these people want in on it early, they can buy it, play the first half, and know that their money is going towards finishing the game, which they will then be allowed to play when it comes out.
