The use of "self-hosting" is a little confusing here. To be clear, he wasn't self-hosting his video. It was published on YouTube, and the guidelines and procedures in question are Google's.
Edit: I'm not defending Google's actions. It's just that the title gave the impression that a video he had self-hosted was somehow subject to "community guidelines", which didn't make sense.
Edit 2: Ten downvotes in less than an hour, on a clarification comment? Wow. I'm disappointed to see that level of targeted negativity here. What rotten behavior. :(
