This is worse than that. I know the types of people who have browsers full of ask.com/aol/etc toolbars. They aren't technically inclined. They don't even recall how those toolbars ever came to be there and they never wanted them.
They aren't able to see through the tricks. They want to download software. They know that's the goal. Installers simply have to keep offering them opportunities to download software and they'll keep agreeing to it to achieve their goal.
