EDIT: DarkkkPhoenix said it better and shorter, but I'm a compulsive writer.
StingingVelvet: In any event my point is more that he comes off as a jerk looking to screw the people providing his entertainment.
If you mean the OP and/or people who buy games from deals, or waiting until the game is old, "we" can't screw the industry because they are setting the prices, not the consumers. If Blizzard wants to keep the prices of its old games higher than other games from the same era, fine, it is their prerogative. It may mean either that I buy their game for that higher price, or not buy (nor play) it at all.
Or, if they want to collect a monthly fee for playing their game (in this case WoW), fine, all power to them. But it also meant I didn't want to purchase the said game, but Blizzard did fine with WoW anyway without me. It is totally up to them, they set the pricing scheme.
Saying that I am screwing them over by not either buying their game, or postponing buying it, is ludicrous. There are lots of goods and services in this world that I either don't buy, or try to get as cheaply as possible. Take for example gasoline, I try to refuel my car on stations that sell it the cheapest, even if some of the gas stations are having hard times with low margins etc.
In my mind the only way I could screw them over is piracy, that's why I avoid it.
There has been discussion here about how some people can't afford games, hence they need to pirate them. For these people, I think it is only a good thing that there are different pricing of different games, depending e.g. on what the development costs are, how old and unwanted the game is etc.
Mass Effect 3 may be too dear for these people, so maybe they could buy Fallout 3 for $5 instead, or some GOG game.
