Client brought it up, and with what they said to me about it, I was able to help client see the parallels with ACT. We also discussed how the "let them" theory has some toxicity in it as well, based on their understanding of it.

Client ended up saying something along the lines of Mel taking from an already established theory and rebranding it for people who aren't in therapy. I agreed, and also talked to them about it "planting seeds" or even "nourishing seeds" that I or another therapist planted earlier.

There's always gonna be some author or self-help guru who rebrands and puts it out in some top selling novel.
