Indigenous Rising

so there is a woman who has grown up children, who are native american, and she is white. she did right by them by getting them involved in their culture because the father was not in the picture. However, she is a vendor at several powwows, selling her jewelry and bead work; and some people are talking about her exploiting Native Americans. She is making money by selling Native style jewelry and bead work, and she is not Native. I can understand why so many people are offended. Advice? Thoughts?
