Setting aside the actual legitimacy of whatever complaints you have about Musk, you aren’t “supporting” him by using Grok, any more than you’re “supporting Xi Jinping” by using DeepSeek, or “supporting Jeff Bezos” by using Amazon, or “supporting the CEO of Exxon” by using energy. Or “supporting” any of a million other people you probably don’t like simply by existing in the world as a consumer. What you’re actually doing is called spitting in the wind.
Major conglomerate providers of commodities are not controlled, or even operated to the benefit of, any single person. Musk is the operating officer of a corporation of many thousands of individuals. He has shares in that company, but so do millions of other people. It would be far more rational if you could point to some specific “evil” thing SpaceX is doing as a company that you oppose, but you can’t even do that. It’s all gotta be about one guy who you don’t like.
