That's the most constructive takeaway you have when looking at all their work? That's an unnecessarily limited view and doesn't add to the conversation.
From my vantage point their work fits the definition nicely.
"A collective body" [1]
...
"Collectivized or characterized by collectivism" [1]
...
"A political or economic theory advocating collective control especially over production and distribution" [2]
I wouldn't say it's a completely throwaway dis. As much as I like Orca it easily could be that calling themselves "a collective" is putting on airs or pretending to be a bigger movement than they are. But it could also be tongue-in-cheek, self-parody, or theater of the absurd (which seems more likely).
