Actually, I have a theory on that. I think they got permission to use the images in the original BattleDroids game and when they changed the name to BattleTech for the second run of the game, they just used the images again. Of course in the world of business, f you cange the name, you change to product, and with Battletech hitting it big, the Robotech guys decided to collect a bit of cash for what they saw as a violation of their rights. That is only a theory, mind you, but it holds together in my mind.
