Perhaps it comes off that way to you but I'd be willing to bet it doesn't to the great majority of readers, because it simply isn't saying what you say it's saying.
OK, but he's worded it wrong, it gives the impression of a snarkiness. Maybe he's saying that matlab users can't program well but are still intelligent/well paid (but that doesn't really make sense since numpy is equally easy and an intelligent/educated person wouldn't find programming hard). Anyway, maybe I misread it and you're right.
edit: great, I was getting points before, and then you come along with your italics.
