I mean just look at her career.. she started it as a kid who decided not to go to school (every kids dream) and tried to use as an excuse that it was some sort of climate protest.
That would be like a education activist protesting the lack of good education by dumping oil in a river. It did nothing to help advance climate change concerns and ultimately was just an excuse for her and others to not get an education (which may have been a useful tool in addressing climate change).
But she got famous for it, and the more famous she got the more she continued and just like the self-serving interest of not needing to go to school, now her fame is that self-serving interest. I mean lets face it, she was a poor student and really has no skills of anykind to make an actual career or to make any real change.
