I remember back in University for the first few years watching a lot of TGWTG content to break the grind of studying. Video games would take to much time, but I could load up a video while studying then watch a show, then go back to studying. Of course, that wasn't exactly how it went as time went on.
Speaking from my experiences, I just fell out of the channel over time, as most of them seemed to be just reviewers screaming half the time, doing really childish stuff that after a while just got super annoying. The only one I watch from time to time is Angry Joe, but he might be his own thing at this point. I stayed with the Weekly Manga Recap guys for a while, but not anymore.
Another thing for me is after University, I started offshore work, where I would be gone for weeks at a time. This means that if I really wanted to keep up, I would have to come home then catch up on 5 weeks worth of stuff. Instead of watching those guys, I can probably find that movie on a boat, then watch it and get more entertainment mocking it myself.
Still sad to see an old friend break up like that though.
