Nope. It falls squarely under criticism and commentary. Let's look at the four pillars:
- Commercial versus noncommercial: It's a YouTube video. Assuming it wasn't monetized by the person who uploaded it, it's clearly noncommercial use.
- Nature of the work: It's a piece of software, and you're reporting a bug. That's a lot closer to factual use of nonfiction than borrowing bits of a fiction work.
- The amount and portion thereof: Assuming it's a short clip, that's very small and very little.
- The effect of the use on the potential market for the original work: This clip clearly cannot serve as a replacement for the original work. (Any other, non-replacement use, such as loss of sales because of negative commentary is *not* relevant for fair use purposes.
So unless the original poster posted a three-hour clip and monetized it, I think it's safe to say that this usage falls so solidly under fair use that no judge in his/her right mind would disagree.
This isn't some security researcher or something, he's a dude who has a side-hustle making new world videos. He posts between 1-3 videos a day, most of them about 10-15 minutes. All the videos I checked were monetized, a calculator estimates his income to be about $50 a day. So, totally commercial.
The part where he demos the bug takes about 1 minute, the video was a 12 minutes long, entirely of in-game footage (as these content creators do, he just talks a lot and goes around and around to pad the video to be >10 minutes for the extra ad). So it's not like he was even trying to spread the word, just create content for his channel.
Correct, this clip would not replace the market. One could say that being able to watch so many videos of a game might discourage people from buying it. I've not purchased games I might have otherwise because I experienced enough of the game via YouTube or Twitch. But that argument hasn't been used in courts so who knows how it would fly.
So, it's not as clear cut as it seemed.
[The video has been since put back and he got an apology from Amazon they blamed a glitch. Maybe they've been testing a system to try get rid of expolit instructional videos since the game has been such a dumpster fire.]
