I had this issue with a less controversial topic yesterday. I was trying to explain VACnet someone and wanted to link the original talk. Youtube didn't have it anymore. 3kliksphilip covered the topic and he linked to the video. It said the video had been removed, though not why. 3kliksphilip's video helpfully said it was a GDC 2018 talk in the first sentence, so I searched google for that and found the video hosted on another site. I don't think censorship was at play. I just think the world of mutable data is volatile and impossible to keep a 100% accurate up-to-date index.
