The thing is though, Rob was legit funny, at least at the time (I'm talking like 2016-2021 era). Yes, anyone can make the style of his videos, but it's difficult to be entertaining on video consistently the way he did. He had a way of telling stories or ranting about subjects that made him mad entertaining at times. Especially if he was raging at a certain game. His humor really kind of went sour the last few years because it was just the same shit over and over. I'm assuming the drugs fucking up his brain didn't help, either.
You guys are gonna laugh, but the shitty camera/audio was part of his channel's charm. It felt like "old YouTube". Even Mutahar kind of touched on this point in the several times that he's talked about Rob. His minimal editing and the fact that he would throw around slurs from time to time made it feel like a time capsule of 2008 Internet culture. There was a REASON why long time fans kept tuning back in to watch his stuff. Ironically, this was all unintentional - the fact that Rob was a lazy sack of shit kind of unknowingly worked out in his favor for a long time during his Youtube career.
Conversely, it's a horrible idea to make low effort content like that forever and expect to grow an audience. Anyone with half a brain could figure that out.
