Since you've been registered here almost two years, I would hope you'd be aware that snide comments are discouraged here, regardless of context. I have yet to hear why you are more qualified to speak on the topic than anyone else, but I will add my personal experience as a student - I went to some good schools and had some good teachers, but we were rarely introduced to a topic in different ways. For one thing, there simply wasn't time.
The best math course I ever took was geometry. The teacher never lectured - instead, he had written a worksheet of problems for us to do during every class period. Each worksheet would start out asking deceptively simple questions, which built upon other questions or challenges to prove something true. By the end of the worksheet, you had taught yourself a new concept in geometry (or proved a series of fundamental theorems) without really realizing what was happening. If you got stuck, you were encouraged to ask the students next to you, or the teacher himself, who would wander the classroom providing hints and alternate ways of approaching the problem.
There was a textbook, but we only touched it for homework problems (and occasionally as a reference).
I'm not going to defend parfe but I will point out that just because you may not have been offered three different ways of learning a subject doesn't mean the school was only offering one and only one way of teaching it.
The original article is saying based on a simple test you can throw half of the students directly into a 'learn to program' class and the other group into something else (I wish they had explored that a bit more). At no point is the student offered a choice. From their perspective the school only has one track.
Now, your school may indeed have been terrible... but I think the point that parfe was trying to make (ineloquently) is: don't presume that your one experience makes you an expert in the system. You probably weren't even aware of things going on behind your back in your own school, much less all of the other schools in the 'education system'.
This is one of those things like graphic design.. Everyone has an opinion; some people have training. Those who work in the field might come resent those who have opinions without knowing about the training.
