Contributing to a foundation may be a trap too. If you assign your copyrights to a foundation, in many jurisdictions you no longer have control of the code you wrote. That means they could license the code in a way that you wouldn't do.

Yes, but that's where the "foundation" part comes in. If it's one whose charter explicitly states that it exists to support open-source software development, it is legally unable to do otherwise.
