If nothing else, in the past, I've run across game content creators who license their work under permissive licenses like CC-NA, but ask that people not stream/YT. So even if it's legal, out of respect for the creator, I prefer to make sure they are ok with it.
I suspect in this case, if there was a reason against streaming/YT of UQM, this post would have been mobbed by people saying "don't do it"
