Aren’t logos fair use?

That’s a very broad question. For one thing, fair use is a concept only in US law. Other countries may have their own versions of it, but all of them have their own unique limits. Even under the US version, it is not at all clear that it would fall under fair use. If I start making t-shirts with the Facebook logo on them, is that fair use? No, it isn’t. Is there much difference between that and putting it on a website that I make money from? The right jury would say no.
