If it costs that much where is the money coming from? And why is it free to use, I dont know if they have a paid version or not but having to pay for it wouldnt interest me.

It might be free in monetary terms, just as Facebook and Gmail are also free.
Right now it's in the testing phase and they are likely using you as a user to help tweak and improve the system.
I believe they are launching a paid version that gives you priority when it's overloaded.

In the words of Andrew Lewis, “If you are not paying for it, you're not the customer; you're the product being sold.”
