The video had nothing to do with WGBH at all. It‘s called „Energy — The American Experience“ and was created by the US Dept. of Energy in 1974 and is quite clearly in the public domain as a government creation (and in case you‘re doubting it, the federal government itself lists the video as „cleared for TV.“

WGBH, on the other hand, has nothing whatsoever to do with that video. It appears that some clueless individual at WGBH went hunting for any videos having to do with the PBS show WGBH produces, called American Experience and just assumed that based on the title, the public domain video that Malamud uploaded, was infringing. Because that‘s the level of „investigation“ that apparently the censorious folks at WGBH do when looking to issue takedown notices.
