By the way, this article wasn't really about Operation Rainfall. It used that as a springboard to discuss Nintendo's mediocre interaction with its fanbase online, in general.
I've never understood why Nintendo hasn't gone out of its way to court third-party console developers (aside from wanting to keep their console audience to themselves). Their "opt-in" policy comes across as more of a "you're welcome to develop for our hardware, but you're on your own" policy. They made the Wii hardware completely different from PS3 and 360, making it less appealing for third-parties to develop for the system because they couldn't spread development costs across a fourth platform (like they could with PS3, 360, and PC). Nintendo made Wii the odd man out by design.
Then the lack of a packed-in traditional controller made it motion control or the highway for third-parties, resulting in many of them abandoning the platform. They knew that fans of their games didn't want motion control (or at least the mediocre motion control on the original Wii; heck, most of them don't even want Move or Kinect either), and their games didn't benefit from it anyways.
Funny, the DS never had a problem with third-party support, even with its goofy control setup. Handhelds have always been development islands, so spreading development costs across platforms was never an option to begin with. However, the fact that it was an island was offset by the fact that it was cheap to develop for. As a result, plenty of third-parties jumped on board.
I think the "Third Parties Hate Nintendo" rhetoric is ridiculous. There's no emotion involved here; the game industry is not the NWR Forums. It all comes down to dollars and cents. Funny how Epic has pretty much confirmed that the Unreal Engine is going to come to Wii U now that it's HD...wait, weren't they reviled as Nintendo haters last generation? Oh wait, didn't John Carmack hate Nintendo too, but suddenly he's talking about bringing id Tech 5 to Wii U? Yeah, but these third parties HATE Nintendo. They HATE them. Nintendo's actions have NOTHING to do with it. Right.
