Indigenous people do not have a right to demand "return" of everything
that they gave or sold to Europeans, nor a right to
control
all the ideas of their culture.
No one has a right to a monopoly over a cultural practice. An
Australian indigene has no more right to enforce ownership over a
style of artifacts, or all its examples, than an American has the
right to enforce ownership over jazz, rock or rap. And people have
the right to make fusions of these with other styles, too.
If you don't like those fusions, don't watch or listen to them.
