The article is correct in identifying a clear separation between religious Buddhism and therapeutic Buddhism.
I find most Westerners underestimate how very, very similar Buddhism is to other religions in practice, because they assume religious Buddhism resembles the therapeutic Buddhism which is so popular in America.
In reality, religious Buddhism is as varied, ritualistic, and even as anachronistic as Abrahamic religions. (The anachronistic description is my probably wrong perspective on all religions, but it is true that if you consider Judaism outdated, than you should also consider Buddhism outdated as well.) The four noble truths especially are not something most religious Buddhist incorporate into everyday practice -- it's usually more about chanting for death points and other ritualistic things.
