This piece generates some extreme reactions. I've posted it elsewhere, among people I know better, and even in that context some interesting argument developed ... although the arguments remained respectful.
I think your interpretation is the correct one. I think that's what the author intended, and it's basically how I see it.
There's another level to it that speaks to a phenomenon sociologists and others observe and occasionally try to quantify. How is it that stuff becomes popular when popular stuff is so universally panned? How is it that Bob Dylan, for instance, is a "sell out" after making a commercial but was the king of counter-culture when he was making millions from selling records? How are so many people so easily able to ignore the irony of paying $3 for a cup of coffee with a Che Guevara image emblazoned on the side? Etc.
The piece makes people uncomfortable, especially those who think of themselves as a part of the "counter culture" or who make it a hobby to criticize those they believe to have sold out.
A friend of mine summed up the piece in an interesting way that I also agree with. He says that the piece crystallizes what most old people know. It's what causes so many young people to think old people look and dress funny. These old people have played this game all their lives and finally got wise, abandoning form for function. Or, they don't care if it looks good as long as it is comfortable or has some utility.
And to answer your initial question, I follow the RSS feed at

OnEdit: I assume you browsed the rest of the site. It definitely has some interesting pieces to challenge your noodle. It attacks, in a humorous and fun way, a lot of people's assumptions and sacred cows.
