I don't think the author would mind carpenters getting together to work on their craft, or working on their craft privately. He says in the article that the basic idea of programmers getting together sounded good to him. Rather, he would be put off by carpenters getting together at an event called "SuperHappyCarpentryHouse", with the stated goal of "creating a key to unlock a door to a better world for humanity." What he doesn't like are the peculiarities and the strength of the culture. (The culture of these particular folks he works with.)
