Calling other people’s work “garbage” is not conclusive proof of arrogance, if that work is actual garbage. Linus has calmed down a lot over the years, yet at this point if he still has issues with somebody’s work, it’s probably best to listen rather than calling that arrogance.

Personally, I do believe the quality of Linux kernel has a lot to do with having a steward able to be firm and opinionated, rather than adopting a passive anglo management style where confrontation is avoided at all costs.

And critique of the work is expected when the quality of the work is the question. But all the problems here are about conduct, which doesn't seem to get through.
