I'm sure if Warner Bros had to pay MGM for the use of Leo the Lion they would have scrapped the logo from the films long ago! I suspect that when Ted Turner bought the MGM library from Kirk Kerkorian, it included the right to keep the original logos on the films - having "MGM" films was a status symbol for Turner. Kerkorian retained the right to use the logo but he was only really interested in having it for his hotel.
You're probably right about Warner and MGM, but I wonder if it is the case for other studios that own films that were previously made by other studios. The RKO logo and name are owned by a small production company that obtained the rights in the 80's. Maybe they just allow them to use the logos because its good advertising for their company even now.
