All culture is cultural appropriation. It doesn't manifest in a bubble. The staple foods you consume and assume to be Western are all historically the result of appropriation.
It doesn't really matter whether people want to call it yoga or not; we fundamentally have the right to practice whatever exercise we want, no matter our ethnicity or culture of origin.
Attribution is irrelevant, notwithstanding that it's explicitly traced to India already in this case.

Not sure what this is supposed to mean considering that culture is not static, and all cultural elements as they are appropriated help create something different from their source of inspiration, by definition.

I wouldn't put much stake in a wikipedia edit-war that sources op-eds from media as citations, but don't see anything explicitly contradicting what I said - it doesn't make sense to liken India as a "minority" culture. In the first place for being on the global sphere, not local, and in the second their population stands at 1.2 billion. There's nothing minor about it. And it's been independent since 1947. Add to the fact, most people in their respective countries are part of the "dominant" culture.
Calling something colonialism doesn't make it so. Colonialism has a very real meaning: power or control over another group through colonies. You can't just wantonly use it as a modifier. Likening yoga to an act of colonialism is disgraceful.
Proponents can just come out and be candid about the fact that this is really a pissing contest over have-not cultures, i.e. the Indigenous. The insult in a hypothetical appropriation stems not from appropriation itself, but because their sociological group still gets the shaft today in the West, which is being attributed to colonialism. Just about anything would provoke a reaction because of widespread discontent, it's just a power they can exercise, and who can blame them? No one can "own" the likeness of wearing a feather in their hair, and they know this - it's not about the feather.
