To make SE more money, that's all there's to it. They run this game to boost profits, to raise their value on the stock markets and to create extra budget for adding things to this game as well as get extra money for the development of other game franchises.
They aren't going to take it out until it stops making them money, and to be blunt, even with the huge amounts of protest topics like this one, the cash shop is a huge success.
There are thousands of people very willing to pay real for digital vanity items.
