Daniel Micay of Graphene has... A reputation.
At the end of his tenure at Graphene, Micay started increasingly accusing people in many other communities of conspiring against him and harassing him. It elevated to the point of accusing Louis Rossman of being part of the conspiracy. It got swept under the rug for years, but Rossman was the one person to get so pissed off that he eventually outed Micay... And his departure from the organization was swift.
I actually reached out to Micay (IIRC before Rossman outed him) looking for answers. After showing me some incredibly scant "evidence" that amounted to accusations he had written in the past, he started accusing me of being part of the conspiracy too.
I don't like to claim people have mental illness recklessly, but I can't think of many other reasons he behaved that way. The only other obvious one is that he was a massive asshole for no reason at all.
But he's also very technically competent (or at least, prior to stepping down, was very competent), and there's probably a reason Graphene finds so many Android bugs and gets their patches implemented so regularly. But the whole thing definitely taints the project and some of the pages he most likely wrote.
