I don't think everything Ilja van Sprundel said is false. He is a professional pentester who looked at source code and found bugs. He said a lot of bugs were low hanging fruits and I can believe that general opinion has some merit.
A the same time I don't think he is competent enough to predict future of *BSD OSes. For example many think that being out of commercial enterprise market is the death of OS. OpenBSD is probably generally out of that market, but... so what? OpenBSD is now introducing oneself as research project and development continues
