Children want to please their parents and mimic their views. It's not a great idea to push young children into the media spotlight. It rarely turns out well for the child.
When a child makes it to a top tier of media attention parents are always involved. Children do not have the drive or capability necessary to do such things on their own. Of course the parents say it was all the child's doing, because the real story is not inspiring and actually somewhat ugly.
So you don't know anything about Greta, and has instead this made up story of her that isn't supported by any evidence, and you make up things about what you imagine children are to support your made up story.
You aren't worth the time. Bye.
