Watched the video & this guy is either heavily biased, as in involved personally in the first Libreboot project, or he's a moron.
He pushes some small issues out of proportion & makes a big deal out of it.
It's natural that, anyone naming their product "GNU" something is getting a cease & desist. It's not like they are evil, it's that you are forced to do it by law, because if you don't send it out, at some point anyone can use your trademark since you allowed this one company to use the name & without sending them a cease & desist.
On the other side, naming your project Libreboot is fine, if it's not a registered trademark or anything. Not sure, if it is, in this case, but still. GNU is a huge thing known around the entire world, while Libreboot is a tough bit deeper in the Free Software rabbit hole.
There's also no such thing as a "hostile fork". If it respects some GPL-like license, it may not be "hostile" or else the License type just wouldn't be good enough to survive in the real world.
The guy in the video really needs to get real & educate himself about such stuff, before ranting about it to his peers & fans.
This feels more like a "I want more views" type of video.
At least, that's the impression I'm getting, when I see this guy for the first time, don't know what he does, how he does & what else he does.
