"It's free advertising" is an argument I see a lot, but I've never seen the numbers to see how much that actually matters in the real world. Well, I guess I've seen some, but it's always from ad companies anyways.
I own a media production company. We occasionally sell content to other media outlets. Early in our existence, we were routinely contacted by reporters asking for permission to use our content with credit to us. I used to respond by saying yes, but only if I could use some of their content, with credit to them. Obviously, they never agreed.
