Torvalds is known for being flamey towards kernel maintainers, but most of the time that is for good reason. Here however, he should just admit he made a mistake instead of doubling down. Admitting your own mistakes is a mark of a great maintainer as well.
Torvalds is exactly the sort of person I'd leave a company to be as far away from as possible. He's brilliant but absolutely insufferable whether it's deserved or not. Anyone with admin access who leans into a pissing contest after breaking the build because they upgraded their operating system just before a release rather than taking the hour to fix the mess they made is going to make you hate your job. God bless the well-mannered kernel maintainers who grind past it.
