This reminds me of this video. I linked it here once but I'll link it again.
This here was infinitely more genuine than Linus will ever be. Steve was just roaming around a Microcenter, and then a fan noticed them and then Steve helped him out pick out all the parts needed, and by the end of it Steve paid for that guy's computer, and the only way you can tell he did that is if you pay attention to the video itself. Neither the title, nor the thumbnail, nor the description said anything about Steve buying a PC for that guy, he just did it and never boasted about it.
If Linus were to do a video like this, the title, the thumbnail, the description, all of it would be mentioning how much of a good guy Linus is for buying someone a PC out of his own pocket, and he'd probably stage the shit out of it rather than spontaneously going to a store, getting noticed by a fan and then going with this schtick. And as everyone in the world knows, if you have to tell everyone how much of a good person you are, you're probably just a massive piece of shit.
