The code wasn't only published, but also was distributed in a binary
form to end users. This means that even if Ouya Inc. still existed and
they made a mistake by using GPL-only symbols plus GPL-incompatible
license for the driver, then they had to resilience the code. Hence
either way it's okay to use downstream code as a reference for the
upstream driver.

This is my understanding.
