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

Games like sleeping dogs are not selling anymore so giving them away for free will probably end up people buying it's dlc and gaining money that they otherwise wouldn't...

Sony does give money to the devs for putting their games on PS+. so in the case of Bioshock infinite. 2K made money from the sales they made at launch, but lets say legs arent too strong and they expect to make like 3 million dollars in sales. sony could come in and say "well, here is 3 million and lets put it on PS+". 2K would make MORE money this way, since it would continue selling to non PS+ members and they would have made the 3 million they thought they would. and it would put the game in more peoples hands, so if a new game comes out, PS+ members would have broadend the audience for the game. so it helps with marketing and generating revenue. this is just a hypothetical example, of course. 

also, as you said, it opens the door to more money from DLC purchases. 

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+..
