Her shift in tactics comes from her realization that 1) that climate change is only a subset of a bigger issue, that is capitalism and class conflict; and 2) the “peaceful” activism she used to adhere to, had she continued on that path, would've turned her into manipulatable tool by the liberal propaganda machine, where she would be used to greenwash corporate interests.
She is free now more than ever, so I disagree with your sentiment, particularly when she is opposing the mainstream media and the capitalist-fascist global order. The old tactics you espouse so much were a sign of her bourgeois, idealistic naivety, which thankfully she got rid of or is working towards that.
And weirdly you keep throwing "they" around, which is too conspiratorial in my opinion.
