I guess it is a bit unfair to put all the blame on the developer. Part of the reason why I don't like DRM is that it's just the fallback for when you can't think of a way to make the model work. Now it is different for developers rather than music artists though. But still there are creative ways to get people to purchase the product, whether it be adding an online component if your making a game, or maybe an online service (see ReadItLater or Evernote). Granted not every developer can do these things but I feel that DRM should be the very last fallback option a person uses.
