It's because Chris is fucking old. He's over 40 now. Back in the early 2000s is when he was capable of juuuust understanding social media. These days? He's got no clue. See how he doesn't even know what OnlyFans is, and barely gets any pop culture references. As for TikTok, that might as well be Chris sitting in the Alderman library, as the quote goes:
Chris has never been able to edit for shit, let alone understand the idea of places like Twitter in terms of how you present your media. Fuck, he's still stuck in the Facebook era of writing long, drawn out posts that span an ungodly amount of tweets. Imagine trying to convince him to do a 30 second TikTok of Sonichu and him not grasping why it can't be a 10 minute video.
Chris is middle aged. He's well beyond a point where he can just jump into a new avenue for expression. I mean the man was getting winded just sitting and making stupid noises in this latest live stream. Long gone are the days of him jumping up and down, screaming and doing barely a fraction of the antics he's known for.
