Two thoughts:
The NRA, like so many organizations, has reached a point where the board can't effectively make a lot of changes. The United Methodist Church in the same predicament with not enough majority to change the theology and not enough to censure the rule breakers. Some sports and hobby organizations have, or have had, the same problem. And of course Congress can't do anything to change the course of the Titanic. They shuffle deck chairs, pick out new music for the orchestra, some shout warnings about a pending disaster, but in the end the ship just keeps going the same way.
NYC has been bent on exercising very questionable court cases. Civil cases are being used to control people in the city and by a big stretch in the whole country. The cases against the NRA, WLP and Trump are just them further flexing the power they gained from lesser known and lesser publicized cases. Cases like Wallace/Adventure Outdoors, where they sent "agents" to make straw purchases then file a civil suit on behalf of the people of NY. (The agents were not Feds, nor was this operation approved or run by BATF, nor were any criminal charges tendered.) Wallace took a plea because there's no winning in their kangaroo court. Like Trump, he found himself guilty before court started. The court case was just to assess how much the penalty was going to be. This is a very dangerous path NYC has gone down. Unchecked they could sue most any manufacturer, retailer or even outspoken advocate anywhere for the supposed "damage" they'd done to NYC residents.
