This attitude is breeding the jerks and aholes in this industry. It is far too common to encounter teams and communities where in professionalism is accepted on a sliding scale of "accomplishment". If you accept this type of disrespectful/demeaning behavior from one "special" person then you will get it from everyone. Eventually, people tire of this type of nonsense and leave. You may be able to backfill their talent, but regular churn per mantle inhibits the creativity and velocity of the group. Linus is extremely fortunate that folks are paid very well to take it, and many very large companies (e.g. IBM, Red Hat, Intel, etc) have a significant portion of their long term livilihoods dependent on Linux.
Specifically the issue is that if offensiveness is considered a perk of being amazing, then people who think of themselves as amazing are more likely to be offensive to demonstrate that they are amazing. Sounds silly, right? But that is what leads to prima donnas.
