There is no solution. They have already taken over the forum with the full approval of Jim Robinson.
As for Jim Robinson, I am grateful to him for providing the forum, and I'm not sure how much he personally influences this site's contents. FR is not like Little Green Footballs, where posters must praise and agree with the site's founder or be banned. On FR, individual posters have quite a bit of freedom, and they deserve full blame/credit for their posts.
Take the best, ignore the rest.
No, no, no. Please change your mind. If you deplore FR's decline, don't contribute to it by leaving.
