What they don't take into account is the secondary and tertiary effects of doing things like this. I stopped visiting channels that did the faces, LTT among them, and I also (usually) insta-close any video where the presenter is making a completely fake 'why don't you tell me about it in the comments' calls to action. The things is that your numbers might go up and your audience might grow, but these tactics work because you are appealing to the trend at the time. People see stupid face and click and the trending metric goes up and you get more hits -- same thing with user interactions on comments. However, two months later when someone is trying to find a video about how to hook up their AMD CPU De-hot-an-izer to a radiator and they see Linus making a Macauly Culkin Home Alone face they pass, and you lose a potential actual long-term subscriber. Also, people with standards tend to be really happy when those standards are at least partially met, and tell other people about it. On the flip side, people looking for their youtube 'stupid faces video fix' tend to forget what they saw 10 minutes later.
