I don’t understand why this is sleazy TBH. It’s CC-BY-SA. If attribution isn’t provided it’s a valid case. I once uploaded a map of my state with all the districts in labels in English and my language Tamil to commons under CC-BY-SA. It was used left right and centre, from publications, map sellers to the point I can see them hanging in offices. It’s always pained me, nothing could be done about it. Now I didn’t want money, would have liked the recognition, but would have settled for just seeing the CC-BY-SA logo on it at the least.

CC-BY-SA-4.0 fixes the specific technique of spreading one's work through the commons and then charging for inadequate attribution by allowing for a 30 day cure period on notification. This anti-copyleft-troll clause should likely permit your use-case.

Ah! I see. My biggest annoyance was none of the derivatives ever made it back to the commons.

it's sleazy because the intent wasn't to be properly credited, it was to use a loophole in the CC-BY-SA license to sue people for minor typos or mistakes in the exact form of the attribution even when they had clearly intended to give proper attribution.

I get what you are saying now. That does makes a difference and actually hurts the copyleft culture.
