Is it right? Maybe. Maybe not.
Of course there is this line, where some people are doing it in professional context and are expecting it to be... professional. In every level. That I find a false expectation, as LKML and this "terrible" culture has a public track record of a few decades. Of course not everyone can choose what kind of work they do and which projects they attend to, but someone working in IT corporations probably isn't one of those unfortunates.
I don't find it amusing, that someone's feelings have been hurt. But on the other hand I find it a viable alternative for all that wasted time on correctness, when someone's idea or implementation is terrible, but no-one can tell it directly, that this really is crap.
