TINSTAFL is universally known although doesn't do much to refute or augment my point. Merchants / busniess often take one for the team and truly offer something for free as in the consumer doesn't pay at all. Some offer it "for free" (rather "complimentary" ) with the purchase of something which is what grinds my gears.
Protip: Throwing more money at the same number of developers does not magically make them work faster nor does it magically make a task any more feasible. I'm not sure how you came to that conclusion but there's some reality for you.
What is "social gaming"? Is this to mean playing online with friends (if so, World of Warcraft takes the cake on everything and that's a successful game).
Or do you mean the low quality style of games in the app stores (Angry Birds, Flappy Bird, etc)? That's nothing new. If anything that's the next generation of those Tiger Electronic handheld games that are outright terrible but everyone had some form of it.
