With due respect, I think both you and the author of the "insecure" article have some fundamental misunderstandings about OpenBSD and the way the project works.
Just to note I don't speak for the project here, this is just my impressions from being involved for a short time.
Firstly, jokes about theocracy aside, OpenBSD is not a dictatorship. There are a lot of developers, and they don't all agree about everything.
So, even if some OpenBSD developers say they are skeptical about MAC, it doesn't mean all are, or that there is no way to salvage it, or that any code involving the term MAC would be dismissed out of hand. It just means that as it is now, well, they are skeptical. And nobody has appeared with suitable code to change minds. And perhaps that developers are tired of hearing about it from people who manifestly aren't going to contribute.
Secondly, in OpenBSD, contribution drives everything. People who write articles or feature requests or posts on Slashdot are taken much less seriously (if they are taken seriously at all) than people who contribute to the project. Many other OSS projects are the same, but in OpenBSD it is very plain.
Thirdly - and this is something most people seem to miss - any MAC implementation must meet the projects' goals (which are something that no current implementation I have seen does, and certainly not one which anyone has submitted code to implement in OpenBSD). At least it must: be good code; be appropriately licensed; be simple and understandable; be documented; and (important!) be secure by default.
So, if you sit down, design and write a MAC framework that meets those criteria, it will be properly considered. You will have to fight your corner, of course, and make a case that persuades others why it is useful, and accept review and make changes if necessary, but if you are prepared to do the work it will be taken seriously - it may not be accepted, but it will be given a lot more weight than writing an article about it.
The fact is that until someone is prepared to stop talking and hack on MAC support, this whole thing is really a nonissue inside the project. All developers have their own interests (sometimes many of them) and at the moment it is clear none of them care enough about MAC (whether it has benefits or not) strongly enough to get involved.
