No one's sure.
He used to stream a lot and he always came across like a friendly and chill guy who cared a lot about video games and eroge. He's even mentioned how it was the travesty of what Chinese company "Paradise Project" was doing to games like King Exit and Dark Elf Historia that caused him to go into publication and localization of H-games.
But lately he's become reclusive and behaving strangely. He's even banned his own fans and customers from his Steam Discussion permanently for asking reasonable questions about his games.
There's three community managers Remtairy hired. One has been MIA for a long time. The other is the only one who does his job. The third doesn't actually do his job, instead just harassing Remtairy's customers. He's a self-proclaimed woman-hater and if he finds out Remtairy has a female fan or customer, he'll sexually harass her to get rid of her. He's determined to make Remtairy's fanbase a "no girls allowed" club, even at the cost of his boss's sales. That one community manager who does his job says it's okay if the guy does this.
In addition, his community is full of real-world politics. You know, the thing us gamers and pervs generally play games or consume smut to escape from. Especially that one "no girls allowed club" community manager, he's always pushing politics into Remtairy's community, and this has naturally attracted some people who aren't there for Remtairy's games. Like, there's one guy in Remtairy's fanbase who outright admits he hates eroge and wants it to be made illegal in the USA. Remtairy is perfectly fine with having someone gunning for him and his career at his side like that, and has banned people reporting how much the guy is killing the mood or asking him why he allows the guy to gun for their hobbies when they're just there for hentai and gaming. I don't think it's a "keep your enemies closer" thing either, the guy clearly wants to ruin Remtairy's career and Rem is giving him inside access to spread his agenda and gather dirt on his business.
TL;DR: Politics and censorship. Since he'll ban and block anyone who asks him what's going on and if he's okay, we don't know what's going on with him. It's clear he's going through something, but no one knows what.
BTW, love your sig! Ranma 1/2 was my first ecchi manga and I'm loving the remake.
