Are you saying that Linus has been able to review fewer patches because his personality has driven people away, and by being nicer he’d be overwhelmed trying to review code?
I'm saying that the patches he has reviewed may have been given more attention-to-detail by submitters and lieutenants because of his personality, in which case by being nicer he would lend his time to be abused to a greater degree. Note that I said "more patches that are broken/semi-broken/subtly-broken", not "more patches overall".
