It almost doesn't matter what the content is as long as it's more engaging than that actual moment of life.
I have neither TikTok nor Instagram nor Facebook (anymore), but I know from when I had Twitter that the endless videos are engaging. I'm not above having my attention captured by them, so I know not to engage with the networks themselves.
It's precisely what you say: I would like to say I just find that stuff horrible. But no, if I had those apps, I'd be using them as distraction too.
