Derich contributed to DSP's content with slideshow/thumbnail "art," tier-makers, and show suggestions via email correspondence (which I find bizarre because DSP already knew what Derich was because a million people told him and then DSP unfriended Derich on Twitter years ago. Also Derich asked DSP if a child kidnapper should get put in jail or get off with a warning), up until KC/Null made DSP ban him (for all we know they still email each other). And Derich was also by far the most obnoxious, redundant, and autistic (literally) spammers in DSP's chat, who demanded DSP's attention, including saying "goodnight" to him multiple times before he left for good.
So yes, obviously Andy has no problem with what Derich does, only that he does it publicly on Twitter instead of secretly in a Discord. Also I find it strange that Andy was blocking all DSP detractors on sight on twitter, whether they were friendly or rude; this contradicts the whole financial incentive of doing a crossover with another content creator in the first place. I'm on the same page with ABG here in that I smell shit. I've been smelling shit for years with DSP and Derich's email relationship, and now the KC King Arc has amplified it by like 10x. Having Derich in your YT chat is one thing, emailing png's with him is a whole nother universe.
