According to Wikipedia, https://en.wikipedia.org/wiki/Cultural_appropriation is not always clearly negative.
What I was referring to is the existing trend to pick ideas from hundreds of years ago, relabeling them while "forgetting" to mention the sources, and selling them as new in some self-help section in a library. This happens to western philosophy as well, and butchering complex philosophies to make them more palatable is hardly beneficial.
Back to the original topic: it's breathing. Nobody owns breathing. It can't be trademarked or patented. The technique can be renamed and passed on for free or for profit.
As for 'nobody owns breathing', nobody fundamentally owns anything, ownership is just a social construct. Someone owns something if a majority agrees they own it. What's being discussed is a style of breathing rather than breathing as a whole. It's no different to attributing the history of styles of music, dance, food, etc... to certain groups.
It's one of the more stupid ideas from a cluster of stupid ideas.
