Since code talks and talk walks, they are not left with a ton. The Affero GPLv3 fell totally flat. GPLv3 pretty flat (Samba was a big adopter maybe? Not sure what growth they saw after that). Some of the SFC enforcement saw a big move / growth in MIT style licenses (no copyleft elements really) which is a big tragedy as well as a fracturing of licensing (another miss in my book).
So if they can get folks to assign them the copyright, that will let them start chasing again.
I'm not handwaving, I cited the article, the youtube video. This is pretty well known as a debate.
