Jobs and Linus were talking about being discriminating in the things they choose to do for the sake of the things themselves.
The article this thread is based upon is about building trust from potential clients by being honest with them and helping them to solve their problems altruistically rather than trying to line your pockets by taking on work that you're not qualified to do well. This is more of a real-life use of karma.
On top of all of this, why do you use the term "anti-pattern"?
I don't think that word means what you think it means: http://en.wikipedia.org/wiki/Anti-pattern
Who said anything about simplification? I think "the design methodology of simplification" is a) not what the article is about IMO, and b) orthogonal to the idea of the power of not trying to do everything that crosses your desk.
The anti-pattern is that in many circles it's essentially a best practice to do everything. Sales guys sell everything, even if it's not in the wheelhouse of the company. Software guys add features that they should probably have the courage to say no to. Musicians over-do their music (ie trying to show off). So that's the anti-pattern; people realize that sometimes saying no is better than the alleged best practice of always finding a way to say yes.
I will admit I certainly could've worded things better, but I was writing from my phone and that tends to decrease my willingness to craft better comments.
That said, the book "Getting to Yes" which is the inspiration for the article's title isn't at all about always saying yes. It's about principled negotiation. It is an amazing book; there's a reason it's standard fare in the MBA world. I would argue that someone practicing principled negotiation would say no in the situation of the article as well; in that sense the articles title is kinda just a cheesy headline (but still nice, it made me click on it).
Steve Jobs went on at some length about this as well.
I recall reading that he said to the CEO of Nike something like "You make a lot of good products, and a lot of crap. Get rid of the crap."
