Overly cynical comment. Article author isn't a psychologist, so has no reason to be a 'salesman'. Additionally, the question of how changeable an individual's personality is, is a perfectly valid and interesting topic to research. (Unfortunately the article does not mention the title, or provide a link to the research).

If one is seeking therapy they usually do so because they are experiencing some sort of distress in their lives, thus they don't need to be convinced there is something wrong with them - they already know and presumably want to fix it.

Having had a short period of therapy myself, as well as having separately dated a therapist, I would say there is huge real value to that kind of work. It's not a con job. I feel your comment is a little insulting to people who undergo and benefit from therapy sessions.

And unlike the Woodie Allen analyst cliche, it is not something that has no end; a short series of sessions can often be enough to help a patient make huge personal changes that improve the quality of their lives.
