That was a pretty tame bug report! Probably the mozilla guys are embarrassed at all their bugs. What kind of a project bans people for filing real bug reports? Losers!
As commenter fantasygoat wrote: "I've noticed the decreasing thickness of skin on the intertubes for awhile now - blame Generation Y and their interest in form over function." I don't know that it is any particular generation; it's just that people who actually do things seem to have given up on listening to complaints of "aggressiveness" and even "bullying" (what more rational people would call "getting to the point" and those with intelligent vocabularies would call "brusqueness").
