I don't buy anything with a brand logo on it myself, and see it the same way; it's advertising space for something I already paid for.

I've honestly thought about the car thing too, after I saw a car without a make on it (I think it was a custom built thing for some super-rich guy). I was thinking about replacing the logo with something fun, but couldn't be bothered to figure out what it meant for the insurance (believe it or not, it can mean something).
