I don't think you do. He's talking about bands that change with whatever the style of the day is, and do whatever the record company tells them too. No integrity.
Read it slow:
It's not just punk, it's the music business in general.
A proper appreciation of a songwriter is understanding as accurately as possible what he saw and was referring to. Not some childish "gatekeeper" taking personal shots against a neutral third party approaching the lyrics because things might become "scandalous" for said fanboy's psyche. You general course of conduct essentially boils down to a order and imperative: "interpret Zappa this particular way". An attempt to assert dominance, nothing more.
Literally, Zappa writes out three locations where punk and new wave performances were held at start of the song. Yes, it could apply to bands in general, but he it's clear he want to say something about punk. He certainly didn't make it ignorantly. In fact, I would say was quite well-versed and researched in punk and new wave. Yes, some bands did get a commercial contract. Time and Newsweek did write positively about one such band(not based in L.A though).
Properly understanding the context of the song requires mental labor; research to discover information. What are those places like Madame Wong. Which bands in punk did go get a record contract(searching google with the term "commercially successful punk and new wave bands"). Unlike your way of battling, I've actually bother to put in the time to bother searching for the likes of Madame Wong, Starwood, "Whisky a go go". The researching is edifying, as some informative articles do exist to help figure things out, such as:
They arrived with their business cards and with their checkbooks. They descended on dingy rock clubs and dimly lit bars. They talked a smooth game and their shirts were tucked into their jeans. The…

Knowing you, you'd simply label this a pretentiousness. Nothing but mere annoyance to ignore. It's pretentious to research context and present facts about a subject matter, according to raging WilliamM2. It's pure exaggeration and annoying to read about Madam Wong's or the Starwood being actual places punks fans congregated at to listen to punk bands or new wave bands.
I get he has a "general message". What don't agree with is you essentially ordering me to accept ONLY THAT and infer NOTHING ELSE from the song. That I will not comply with.
It's punk bands, new wave, and any other relevant band that played at Madame Wong's etc. Maybe some bands from that era decided to "sell out". Not sure which, but proper research would involve listening to practically every act on the scene and read their history to find out what exactly Zappa was referring to.
Aren't all your pretentious posts crafted to annoy? Or do they just read that way?
Can you cite where in this particular thread where exactly is the pretentiousness? Arguing Zappa is referring to punk and/or new wave or alleging that he actually listened to punk songs when forming the satire cannot be deemed "pretentiousness".
Taking a counterpoint in itself is not pretentiousness nor ispresenting mundane facts in support of a point is not that. If you think, you're extemely sensitive to opposition and also a poor debator. Ad hominems galore, and baldly asserted. You don't try to support the ad hominem with any sort of syllogism.
When it comes to music acts, I take an extremely open approach to processing any act that comes my way. There' only one who is in the basement cellar of disrespect, and that is Brahms. I can't stand Billie Eilish and I believe her messaging is calculated for an impressionable audience, but I will not attack her or her brother's ability to compose after seeing their short documentary on how they compose.
I know about "detail wars" in music. Single elements can result in battles and "schools" of thought. Tempo, can create battle lines amongst pros and fans. Examples include "historically informed performance" in classical circles and their counter-sentiments. Tempo, along with instrumentation, is also part of the change in the Go-Gos music style from before and after they went "commercial"; the skill of the players didn't change but just those changes can turn someone from "punk" to "sellout" in an instant. Faster tempos can result in differing moods compared to slower ones.
