From what I can piece together it seems Hector is upset about someone ("Hellwig"?) doing something that was seen as intentionally sabotaging the rust efforts. Hector posted about it on socials. Linus came down on Hector for leveraging socials to fight kernel disputes. Hector quits. No doubt that is a flawed summary so feel free to correct
Marcan is probably a little acutely upset not just because he was told off, but also because Linus hasn't waded into the actual issue at hand (which he needs to, not even Greg K-h can answer it). But that issue is less urgent and it's probably reasonable for Linus to:
a) Mull it over before making a rash decision b) let tempers calm.
I would guess Linus will wait til Monday and is probably also having some off-list chats anyway.
