It's pretty simple. Because we are all so spoiled and entitled that we won't even consider NOT buying their shit anymore. It's the same reason the video game market has grown rampant with micro transactions. They keep pushing the boundaries, and we keep giving them our money regardless of what they do. I'm actually curious to see how far they can push this insanity. They already slap a new year on sports titles every year and somehow sell the same game to the same people annually.
PUT YOUR WALLET DOWN.
