It is not mindfulness itself that is pseudoscience, but the simplified claims of new/modernized techniques that are put under that name, and their rush to link themselves to state-of the-art neuroscience and experimental psychology. It is worth repeating the (Wikipedia) definition of mindfulness: "Mindfulness is the practice of purposely bringing one's attention to the present-moment experience without evaluation" In this raw simple form, mindfulness is always a net positive (in the long term). However, I agree with you that special techniques (and obsession) can lead to negative effects especially when done without guidance. The reason is simple: Any powerful technique/technology is quite harmful when misused, and the mind is a fragile system.
