I presume this is a rhetorical challenge to the OP, but the answer is an obvious and resounding “YES!”
I don't know much about them, but if they are fine with the SSPX reconciling with Rome, and they are fine with the SSPX collaborating with the conciliar dioceses, then they are not faithful to legacy and work Archbishop Lefebvre. They may have good intentions. But eventually, they will be conciliar Dominicans. And you know what that means.
