I can't imagine being showered with money and acting like that, looking like someone served you a plate of turds or something. I only unironically watch a couple streamers but they all enthusiastically shout out any contributions they get, and if someone is particularly generous will make a big deal out of it to show they appreciate it.
DSP hates his "job" but knows he can always count on a few whales to pay for his mature, adult lifestyle. That won't last forever, however. We've seen whales vanish over time and it'll just keep happening, and I think he knows that but rather than plan for it and save money he just really really hates being in the pocket of his dents. This is why he's such an asshole over the dumbest shit (someone asks him what his favorite X is and he belittles them for their 'stupid question'), acts like a spoiled brat and acts like he's owed everything he gets.
He has that roach luck so part of me expects to be outlived by DSP, I just hope every waking moment of that life is fully of misery, paranoia and self loathing.
