I think it's more rational to fuss about buying a Tesla than about buying a Windows license for a few reasons:
* It's a heck of a lot of money to send to any company, so it makes more sense to pause and consider what you're funding. I can't put that much effort into every <$100 purchase without going crazy.
* Tesla is far more about Musk than Microsoft is about... whoever runs Microsoft these days. There's a very specific person tied to it.
* Driving a Tesla is seen by the world as a statement of some kind in a way that running Windows simply isn't. It's worth considering if that's a statement you want to be making.
