A nasty side effect of consumer-inherent complacency. As long as you keep consumers' appetites satiated just enough for them to want more, this sort of thing by and large will go condoned. People who don't develop Apps on the iPhone didn't care about the crappy developer agreement. People who just log onto Facebook to gossip about Johnny and Chachi didn't care about openGraph. People who only bought Starcraft to build pylons wont care about this.
The casual gamers and casual consumers outnumber power users at least 5:1, and that's what allows these sort of things to perpetuate and continue on the rate that they are.
