The video linked in OP is essentially the rest of LMG that isn't Linus saying basically the right things about the whole affair. Specifically, they claim they will address the near-proximate cause of the factual errors (too much time pressure due to their self-imposed video release schedule), that they will improve inter-departmental communication both to enable fact checking that prevents meaningfully false information from being released and to prevent things like selling a small companies best-in-production prototype without permission. Both the CEO and CFO committed to a lessened video release schedule and a minimum one week off posting, which is significant as it's the channels first time in eleven years that they won't be posting a video every day. Linus does appear in the video towards the end and is, in my opinion, the worst appearance in the video by far as his manner suggests that he really doesn't understand what he's done wrong about at least some of these things, even if he does seem to understand others. Luke also appears and is very apologetic, which feels weird to me as my main exposure to him as someone who is a casual watcher of LTT/LMG is that he is constantly trying to prevent Linus from saying or doing really, really dumb things on the WAN show - maybe he actually has more responsibility for some of these errors behind the scenes, or maybe he has generally higher integrity which caused both the apology from him and him to try and stop Linus from making significant mistakes publicly; I don't know.
That is about a full summary.
The part about Linus appearance in the ‘what do we do now?’ video is on point too.
I would add that the general tone of the video is appropriate, but as LTT is wont to do, they contaminate their sincerity with repeated product placement, ‘in jokes’ and humour. The very root of this ‘drama’ appears to be LTT’s lack of understanding of their serious and influential position in the space they occupy. This video serves or additional evidence of that lack of understanding, but at least a desire to improve.
"The Problem with Linus Tech Tips: Accuracy, Ethics, & Responsibility"
The follow up from GN [1] was interesting as well... ironically many of the techniques Linus used in his response are taught in PR and crisis communications, telling me that they didn't really care or understand the scope of the issue.
