I mean all Twitch streamers can fuck off as far as I'm concerned, the idea of unironically watching someone else play a video game is something I can't wrap my head around. However, if I walked into the next office and told my coworkers they were shit at their jobs and that they were pathetic shills not like me who's awesome and cool, I'd fully expect to get some sort of reprimand if not fired.
I can grasp this general idea, and I usually don't watch streams terribly often. However, when I do, it's generally because there's a specific game I like and play it a lot, and I've hit some kind of skill plateau, but want to get better. Then, I'll watch someone who's actually really good at it, and who when they're streaming, actually explains their reasoning for what they're doing, points out their own mistakes and how they could have done something better, and in general, is actually helpful and useful.
My main example of this is a guy called darktwinge, a Twitch streamer who did FTL: Faster Than Light and is one of the best players of the game out there. It is notoriously difficult, with an "Easy" mode that would be called "Nightmare" in most other games, and basically a roguelike-like, in that the content is procedurally generated and death is permanent (and usually very swift when you are new to the game).
There's a similar guy named lethalfrag who also plays this game, but instead of twinge's incredibly methodical, precise play, he does incredibly difficult challenge runs in a wild, aggressive style. He also has a degree in culinary arts and does cooking streams sometimes where he cooks top tier meals and shares recipes. He's basically the anti-DSP and the anti-Jack Scalfani at the same time.
Good streamers, though, have some things in common. They're invariably polite with their audience, they personally acknowledge any tips or comments and answer questions from the peanut gallery, and they do not gratuitously ban people unless they're being absolute shitheads. Whether they're doing it for a living or just as a side thing because they like the community, they act like professionals. They don't act like infantile morons.
Really, if DSP had just started streaming today with the way he acts, he'd never have gotten anywhere. His sole claim to fame was getting in early and getting "famous" early and now he is only known for being an asshole and for having previously been one of the early people doing this shit. Even then he sucked.
tl;dr there are reasons, even if they're kind of autistic reasons, to watch streamers, but there are really no not-utterly-dumb reasons to watch DSP unironically. The obvious reason to watch streamers, i.e. to get better at something, simply doesn't apply. All you learn from DSP is how to bitch and complain when you play like an idiot and lose. The only real reason to watch him is to watch an idiot fail at something and laugh at him, or troll him and get banned.
