Good grief man, calm down. wth is wrong with you? Valve wasn't "allowed" to switch to online delivery only on some bond of contract that it would magically make you a millionaire. It's an approach they took because they figured it would work for them, and they are seeing what the market will bear.
As for brining costs down, you as a layperson have exactly zero ways to tell if it has or not. Factor in inflation, all sorts of other market shifts, exponentially increasing costs for making games, different game styles, and so forth, and even a real ecnonomist wouldn't be able to tell immediately whether some aspect of the market has changed things or not. But apparently, you, with your power of namecalling, CAN do this.
WOW!
