Linus was the one calling the OpenBSD developers "m...... monkeys" (apparently that word triggers the HN spamfilter, I vouched your comment), so I think the OpenBSD guys are allowed to be "a bit miffed".
I don't blame them for having issues with the way Linux does things (after all they run under different philosophies). But they didn't have to stoop to the same level.
It really wouldn't surprise me if something similar ended up in Linux one day. It just seems so clean and simple for the most common cases and small utilities.
