I'm not so sure that he's as rude as made out either. Choosing just two of the links from the list given which are supposed to show an attitude problem I'm not in agreement. For the first one I initially read it as a bit terse: "this function is a joke [...] don't you have better things to do" until I took a look at the function in question: strfry. It does seem to be possibly a joke, or at least mildly entertaining non-useful function. If there are other higher priority things to patch then it does seem odd to waste developer time on it.
The second instance seems to show people misusing the comment facilities on bugzilla in order to harass the developer.
