It's not clear why this would be a relevant distinction. If the use in question is fair use then copying is permitted. Why wouldn't this be the case for the person uploading the data as well as the person downloading it? Suppose you have a physical copy of a book and your friend wants a copy of a page for a use which is indisputably fair use, so you make a copy for them and give it to them for that purpose. How is that any different?

Wouldn't that depend on what the user is actually doing with it? If you're just watching the game with your friends, presumably not. If you're doing scientific research on sporting events and you need to run the video of every sporting event in the last 10 years through a computer for your study, maybe it is.
