Spot on. Like how Facebook used to be quite useful to stay in touch with friends, or how dating websites used to be kinda decent to find like-MINDED people but have now all been enshittified in order to keep people on them.
I used to not mind my kids watching Youtube on the home TV, but lately when I walk by they are doom scrolling one short after the other. I tell them not to watch shorts, but a day later I walk by and they are back to doom scrolling. I'm finally forced to remove Youtube from the TV. On the phone, Instagram is the same way, I see my teenager doom scrolling it quite often. They claim it helps them relax.
