Well, the article you've shared has specifically to do with cultic groups that use some variety of ideas from psychotherapy as a tool for making members dependent on them, however I think that's quite different than the idea that the article Bud shared presents, which is that a cult-like environment can be fostered even in individual therapy. I'm sure that author has had equally valid personal experience which has given him the perspective he presents. (And personally I do not see any particular suggestion evidenced through his writing of his being in a cult, although if he's had that experience it could certainly have enhanced his perspective -- not invalidated it...)
