I hadn't noticed these; thanks for posting.
There are 2 things to be noted here:
1) I wouldn't trust the test against specifically designed knives for that purpose. Especially with INFI (whose composition is secret) nobody can guarantee that it will be the same INFI that is used in mass produced knives. I would like to see more scientific testing, but against randomly picked mass produced knives, or otherwise it won't have any relevance (at least for me as a consumer).
2) It is interesting to keep a watch on Joe X to see if he comes back public with his videos again. If he does, it probably means that he staged all this situation himself to enhance his popularity. He did something similar about 1 year ago, when he hided all of his videos from public access for a few days and without giving any detail about the "why" (he just said something like "that's over").
3) It was not Youtube who attacked him (that's for sure), because I know how Google proceeds when they do that to a channel. He would have had no chance to post anything anymore and he would have probably had all his Android devices also blocked until issuing an official letter to Google to negotiate for unblocking the devices (they might have unlocked them, but not the channel). You can see that he posted that bye-bye video afterwards, from the same channel, so it wasn't a strike from Google & YT. Also if you watch his playlists, you notice that the videos are not deleted, but only hidden from public access. So I suspect two possible things: either Busse or one of their relatives did him something, or Joe X himself staged all this. I am personally watching this story till the end to decide which of the two I need to hate more (just kiddin'
).
