I'd say he owes an explanation if not an apology to his fans as to why the video was yeeted off the internet for months and now is different than they remembered with a bunch of hacksawed sections. It's not a great situation to be seen to bow to the soyking but it just proves he should have explained things and owned up to a mistake back when it first happened rather than getting caught in a video essay when literally all of this could be avoided.
That's the crux of the issue, a lack of accountability from IH regarding how the claim was dealt with and whatever deal he made with the company that sent the claim, but then again it's a fucking YouTuber, he doesn't have to do anything to his fans/viewers, he doesn't own any of them an explanation or an apology, that copyright claim was his business not the business of his community. An explanation, an apology or a Struggle Session, that sort of thing is extremely common amongst BreadTubers and YouTube as a whole, for whatever sin they committed (A sin for the point of view of their community and YouTube as a whole).
IH, as a brand, company, whatever it is, only owned an explanation and compensation, if it came to that, to the company that owns the article, MentalFloss and by extension to Minute Media, the parent company. Since it is IH who was in the wrong for plagiarizing their article for a video without properly referencing his sources, doesn't matter it if was an editor or an intern, it's his company, his brand, his content, his product, his responsibility.
I think at this point, it's beating a dead horse since until we get the exact details of the deal, we can only speculate. At any rate it has been pretty fun, I had a few laughs seeing Null and the other posters going back and forth over IH section of the video and his cave video these last pages.
Also, fuck copyright.
