And his viewpoint at the time seemed fairly agnostic - he enjoyed the passion on both sides but said nothing about what his thoughts were.

Personally, I'm surprised Linus hasn't gone 100% in on Rust as he is normally very forward-thinking, so perhaps that has added to the frustration from so many kernel developers like Hector.
