Yep I agree too. 15$ for 5 maps is too much. But we, the financially conscious gamers shouldn't be bothered. Let me tell you something - the rules of supply and demand are ALWAYS present. If enough people are so stupid and their system works, they'll continue doing it. But as long as there are conscious gamers, the whole thing isn't "lost". Same thing with boxed games with manuals. Or look at DRM. If everybody would have buyed DRM games, every released game had DRM now.

A nice proverb comes to my mind: There are always black sheep. Think about it.
