DC is definitely a problem, first of all he mostly draws stuff that is really not needed for the game when he could have completly finished the art assets for the rhonda, annie, judith and a couple more character routes completly by now but it seems like he rather doodles wallpapers
He's actually been working on assets for many characters that need it, including Rhonda, Annie, Mrs. Smith, the lifeguard, etc. Just because he releases wallpapers doesn't mean those are the only things that have been keeping him busy. He's had a period when it hadn't dawned on him yet that the tech-update was gonna take a prolonged time, so he was literally doodling on stream and saying "I have nothing to do". But thankfully that period was short and a while ago, and now he seems to be pretty productive.
ultra detailed interiors for every side's characters home and shit like that
Interiors have always been part of the game, and giving some characters' homes interiors in advance of their inevitable update makes perfect sense. The detail to them is fun and appealing. If you'd rather have a stale environment then you can find plenty of those kind of games on this site, but there's a reason SS is so successful and games that are churned out with no heart get abandoned at 0.1.
This really bugged me too when he still did this, DC had a period where he would add new side characters instead of completing the unfinished ones, or add in the missing content that's still not in the game until this day. I haven't seen him work on new characters all that much but I do know he's added a couple. Hopefully they'll remain as purely functional characters until the game is near finished and they get some scenes or something.
second it looks like he doesn't give a fuck what the rest of the team is doing, i honestly doubt he even knows what his coder is doing all day as long as the money rolls ins
Yeah, I don't think he has any oversight of what's happening either. But we're all on the same page here, he's just not good at managing or making a game.
