> My sense is actually that the reason he talks that way is to make sure that people who consider themselves "on the left" don't mistake him for being someone "on the right" (and therefore in camp b), and immediately dismiss his claims.
This is a tad naive I think. "antitrust left" is also to useful term to use to signal to the billionaire class of Democratic party that you are not their enemy. If the author actually agreed with many of the antitrust group's positions and housing policy was one of the few exceptions they disagreed on, they would shy away from using the term. The only reason you would use that term is because you want to bring disrepute to their entire platform.
These abundance folks appear to be the only hope the billionaire Democrats have after having sunk so low as to direct their media assets to support Cuomo and to pour bucketloads money into the coffers of the corrupt disgraced governor in order prevent those "wacky socialists" to gain any more traction.
Since the authors are arguing for removing a lot of current housing regulation, I have a hard time seeing how "the billionaire class of the Democratic Party" would consider them their enemy -- unless, of course they're mistaken for people in class b.

Human beings like to know if the person they're reading is on their side before they take the time to read a long ass article to make sure they are in fact on their side, especially if they're billionaires and think they don't have the time to read long ass articles about housing policy unless they think it's going to an extremely useful to them beforehand. That's the whole point of giving that signal literally in the intro paragraph.
