It’s not as if they didn’t still get paid under the previous model. It’s just not conducive to a profit line that has to be on an incline forever, else be axed or forever altered, such as in this case. It’s greed, pure and simple. They have to find a new way to make the line on a chart go up and people who are more interested in short term gain figured they can wait out the backlash storm and rake in more profit on other businesses that are already locked in. They’re not dumb, they just aren’t incentivized in anyway to be concerned for the long-term health of what they are built on.
