Matthew allegedly being a drug and alcohol abuser actually puts a lot of his more pathetic actions into perspective. It doesn't justify them by a mile, but the whole me-me-me and power-grabby nature of them makes a lot more sense now. This whole time I've just been like "what part of this man's head makes him think this is an acceptable thing to do?"
If the drug abuse allegations are true, then the "making a bullet list of his morals" and "chasing a woman to another social media site where he proceeded to harass and dox her" things make a lot more sense, now with the perspective that he's probably turnt off his ass on Adderall and liquor. He probably hit a breaking point a while ago, and that's why he was on leave. Instead of getting the help he needs, he's probably doubled down and started making things worse by using his newly ample free time to only feed his addictions, and now he's hit a new breaking point by trying to maintain control of a situation and company that he's now facing the reality of losing.
All I can say is I hope he gets help and realizes what he's doing is wrong, but who tf knows if that's going to happen. He's a rich, white, cishet man, so I'm not holding my breath.
