Wait a minute... look at his quote: "* There are very few decent music venues. Among my many complaints about SF, this is one that appears to have gotten much worse since I left; read JWZ's blog on SF's "war on fun"."
You mentioned two groups that are fairly specific in genre/taste. The OP says "There are very few decent music venues..." How does what you mention invalidate what he said? "Two" is a "a few" in my book.
Was responding specifically to: " It doesn't have a noteworthy theater scene, or (to my knowledge) excellence in any of the performing arts."
I was assuming by "decent music venues" the OP was more referring to a rock/jazz/alt type scene, because of the "war on fun" reference. I get that they're not mutually exclusive terms, but I would put symphony/opera in different categories than, say, a blues club. Sorry. I'm a conservatory-trained professional classical musician, and I'd say that most of my peers would read this the same way.
I also see that this has been commented about above, and it's true that Chicago's symphony is equally outstanding. My point was that SF _does_ have a "noteworthy" and "excellent" performing arts scene, found, for example, in its excellent opera and symphony seasons. Michael Tilson Thomas, additionally, is a "noteworthy" and "excellent" conductor.
