Just to inject a little more info into the conversation, the C++ WPILib is BSD licensed. Only requirements are that you maintain the WPILib BSD license notice. So Chris is correct that teams hold the copyright to their code, as with any other work of this nature.

IANAL, but I don't think a team would give up their copyright just because they posted the code on their website. Granted that it'd be much more definite if they actually note the copyright in the code or on the page, etc.
