It's clear hardly anyone commenting here has any idea what appropriation really is. It's not just disrespecting existing cultures.
It's destroying them by removing the meaning from them. And then repackaging the symbols - usually with a vague implication of profundity and exoticism - as a marketable commodity.
The purpose isn't to spread the original culture but to use the trappings to promote the usual Western corporate neoliberal value system.
Corporate Buddhism is a perfect example. It's clearly a lot more corporate than Buddhist. The goal isn't enlightenment, detachment, or compassion, it's cultural conformity with the aim of increased productivity and a higher share price.
This shouldn't be controversial. All you need to do is look at how people behave to see what motivates them.
