Some people don't agree with his approach to programming or emulation related solutions. It can be seen as very NIH as a mindset when you get down to the technical details. As for other things, like the recent USPS incident, some feel he overreacted by initially calling it theft (or implying it was). In reality, it was the fact that he went public that it got a bunch of attention on Reddit and some people at the USPS noticed and helped get everything sorted, but some still feel the outrage was overblow (personally, with $10K+ in valuables, it was the right amount of outrage). His previously cold relationship with Retroarch and Libretro devs was a sticking point for critics as well, but last I heard they were on fairly good terms.
I can't speak about temperament/personality in-depth, but he's always been pretty friendly with me. As a fellow emu-dev, I've given him a few tips on Game Boy stuff (think I was even mentioned in one of higan's changelogs) and it was fun helping him out. I respect him like I do a lot of other folks in the emulation community, but byuu has a lot of eyes on him, and not all of them see things on the same level with him. Pretty sure he recognizes this, which is why on his own forums he has the user title "Polarizing Protagonist". For some, he's kinda become one of those figures you either love or hate, I guess.
There's probably a lot of drama I don't know about, but that's just the way I see it. I try not to get involved with that stuff.
