I get what you're saying, but there are several things to nuance this.
The initial premise, the discoverys made about the fate of the ones who get their accounts terminated, might lead them to a point where they actually have a very visual enemy, and have something to fight against, as opposed to stumbling around in the dark, seeing vague shapes and hints of this antagonistic force.
Maybe their actions are already causing change, using loopholes in the system to get to a result that the system wasn't prepared for, and is ill equipped to deal with.
Maybe, through the progression of the story, it becomes more clear which are the rest of the forces at play... I personally think there is some parallel world or worlds being exploited through technology, and in the end, the player will have to face the choice of either freeing all those entitys, or continuing on with the enslavement... remember, the game isn't exactly approaching the finish line.
And let's face it, when faced with a world like this, how many people's first thought would be "ahhhhh, awesome, now I have yet another world to save! Who cares about pleasure and fun when I can play this game to be as depressed about the state of the world as possible!"
I, personally, wouldn't exactly enter such a world with that mindset, but I think, through the storyline, it will become an integral part of the game to really become the hero... and who's to say being a hero can't mean getting some action, as well, lol
