This is my opinion as well. I also don't think it is dishonest to first show interest in something and then realize on the go that it's not something one is comfortable with and/or has the skills, or even true interest, to do in that depth. This is how we all learn: we get interested in something new that is initially unfamiliar, try it making the assumption that it will indeed be interesting, then make more accurate action-based assessment and conclusions based on "data" (actual experience). Then adjust interest, intention and approach if necessary.

On the shaming issue - that is also subjective, something that sounds judgmental and shaming for one person may not feel that way at all for another or they might not mind the criticism, joking, whatever. (This is where I sometimes run into conflicts with people, for example.) Why feedback is so important. I think what is dismissive is if someone ignores and continues to judge/shame/whatever the other still after clear feedback. If a therapist does that, I think it is especially bad and not the sign of great skill or even emotional intelligence.

As for a therapist not acknowledging that their feelings/issues create a barrier or conflict - from reading this forum, that seems very common unfortunately. Of course if they are not aware of the cause of the problem, there is nothing to acknowledge and take responsibility for, but that does not make the problem go away. Probably the choices he makes on how he works and on what kind of client issues, modality etc already has that factor integrated that he avoids dealing with areas too deeply where his own issues interfere. I personally don't see that as a problem, everyone makes those kinds of career choices. But clearly promising something and then not following up or not taking responsibility for the quality and the consequences of the follow-up is poor practice and can be damaging on the other people participating. I would not consider that dishonest per se, more irresponsible. In that case, I always feel that a T terminating based on acknowledging their lack of ability/skill is more responsible than continuing to make promises, collect money, and not doing their job or doing it destructively. But that's for another discussion.
