I see your point. It is valid.
I was thinking more along the lines of companies who have won their case in court but are still being painted with the Troll brush in an attempt to discredit them while the appeal ad nauseum process goes on..
I always thought they meant "troll" like in the fantasy story bit. They guard a bridge and force you to pay a toll, justifying themselves by making claims they serviced the bridge somehow. Then you have two choices, risk your life fighting them, or pay them.
Same thing with most NPEs, except the bridge is your tech, the service is some weird thing they claim you couldn't have built the tech (crossed the bridge) without, and you being forced to risk your business fighting them in court, or you can just acquiesce and pay them.
