Are the PS+ "free games" the crack that will bring down the industry?

Why would they give so much?  Bioshock Infinite doesn't get new shipments anymore, all they make money on is people buying dlc, I doubt Sony give so much.  If 2K gets money it will be based on people downloaded it from PS+.. 

its just an example. i just made up the numbers.
