It's a curious contrast to companies like Qualcomm, who will release source code openly but keep their documentation very secret. I guess that's why I'm not too bothered by MTK not releasing source code or complying with GPL --- the source only says how, but they've already leaked the why which I find far more useful for modding, or like this project, eventually fully open-source replacement.
 Chinese companies in general have a more collectivist approach to IP. I've heard that the main reason they mark those documents confidential/NDA'd, and yet don't seriously pursue leakers, is that it gains them sales (and "street cred" among the modding scene...) but they can still go after those who use that information to compete against them.

One of the many advantages of the GPL over licenses such as MIT.

I've successfully (with some hacks) ported AOSP to one of these devices in the past.
Kernel source, and some associated flashing information can be found here:
The best way to support the project, without contributing code/documentation/etc, is to spread the word!
e.g. for those with superseded bootable phones gathering dust in a box of old 'junk'.
I don't think they're looking for Qualcomms.
