My original comment boils down to this: even if things were fixed -- even if every reform possible were made -- SSPX would still remain on the outskirts, by their own choice.
The alternative -- the productive way to stay in the fight -- is through FSSP. The Fraternity is the remedy to the SSPX: it returned inside, to fight inside. When one removes themselves from ordinary communion as SSPX has, one goes impotent to work for the change that really needs to happen. Now, you're a non-issue on the fringes.
Sticking up to Peter is great. Breaking away from him because you disagree? Not so much.
