Blame isn't a finite thing, and blaming facebook doesn't reduce the blame that can be giving to the developers. Blame is like the tension in a rope, equal along the length from cause to effect.

Yes, facebook deserves blame. Yes, the game developers deserve blame. These can both be true at the same time.

Out of curiosity, I'm assuming most of the ads are giant in your face ones. Do they do any subliminal product placement type ads too & if so are any of them dynamic based on user data? Might as well go all out & have a variety of props you can exchange based on user data.

I seem to be able to avoid ads quite a bit through tools & life style choices. I therefore ask this as someone whose personal opinion does not like the do anything for views to sell ads economy & avoids it as much as possible.

They are really giant in your face ads yet.

Imagine Billboards in the virtual worlds of your games for now. Image below if you want to see an example.
