You've obviously never worked in an office, or you have taken a big step away from reality. The things Linus mentions are what happens as a result of supposed "professionalism".
When has Linus actually worked in an office? Would he really know what it's like?
AFAIK, he moved from Finland to USA in 1998 to work at Transmeta. He was already famous at that time, and presumably could dictate his working terms. I recall reading an interview that suggested he was mostly working from home on the Linux kernel already back then.
Maybe that's why his notion that "professionalism" equals neckties and backstabbing seems like a caricature out of a '90s TV show.
