Go on reddit and ask them. They'll tell you that Elon Musk aligned himself with republicans aka 'literally nazis'. This outweighs anything positive he could possibly ever do. Any cred he once earned for himself by trying to popularize electric cars? Completely gone, he's a republican so he hates the environment. Building rockets is perceived to be little more than a cynical cover story for his real plan to ruin wetlands and murder ocelots.
