(b) They demonstrated the Pi running Quake 3 at a reasonable frame rate in 2011. There's a picture of it in the blog post.
(c) The competition rules say "To submit an Entry, and Entrant shall email a link to a public GitHub repository containing the full source code for the Entry..." so just showing the result wouldn't be eligible to win. That and they already know what it looks like, because of (b).
And they are now offering a bounty for the creation (refinement, really) of more free software. Which will benefit the entire community surrounding the RasPi. So that is good. Even if they were offering $10 USD, there might be someone who'll take up the challenge just to get the bragging rights.
I don't know if you are familiar with the embedded world, but a large percentage of the offerings (specifically system on chip or SoC) have NDA requirements for the documentation.
And many of these platforms don't have a decent Linux port, even though they could support it.
Even with SoC vendors such as TI, the graphics core for the OMAP4 (for example) is a binary blob. There is no documentation for that, and no hope that situation to change (in part because TI has exited the mobile phone market).
Please tell us of your mobile platform experience, and what vendors you consider open or closed.
You could look at it that way if you like. But if you compare the rPi to the comparable low-priced educational development boards available when the project started (none). You might conclude that their marketing effort had a good and very real effect on the availability of low-cost edu dev-kits for both Broadcom SoC products and others' as well (like the BBB). So, as both an educator and Open Source advocate, I am fairly pleased with the rPi project, and even if it isn't exactly what I would have wished for I can't imagine how it could have been more successful or had a better result.
For most practical purposes, it didn't. What existed were either inferior to rPi and more expensive (>4x) or approximately equivalent and much more expensive (>8x). It has had a significant positive impact on the way instruction is given.
Also $10,000 is a significant amount of money.
