“Successful branding stories are often characterized by disruption, which turns an established industry or experience upside down. The MBSR brand is one such disruptive force, with Kabat-Zinn’s talking points including pithy quips such as: “The Buddha wasn’t a Buddhist,” or Buddhists “don’t own mindfulness” because it is “an innate, universal human capacity.” Potential customers are thereby assured that MBSR is a non-religious product, yet still offers the best bits of what the Buddha taught. In Kabat-Zinn’s words, his version of mindfulness is “a place-holder for the entire dharma.”
The Western world has co-opted an aspect of Buddhism, which works to improve productivity, and discarded the part that doesn't fit its worldview; the other pillars of Buddhism. This enables it to be sold as non-religious.
An important exception is that some Christian fundamentalists regard any form of magic or mysticism other than God's miracles as being inherently Satanic. This can even extend to fictional systems of magic (as in fantasy novels or RPGs), which may be regarded as an obfuscated form of the real thing.
