Getty’s releases free images…

So now that Getty’s has released a boat load of photos for free, the user only needs to add code to the site the free image is used on. So whatever the code does it must result in a way for Getty’s to earn something. IF that’s the case, they are knowingly and willfully shafting their image contributors. Why are they allowed to do this? Is it a right signed away by the photographer thru the T&C’s of becoming a Getty’s contributor?
