Almost the same thing happened with iStock (which was bought by Getty images) some years ago. They used to be my number ones site for making money selling stock footage. Now they pay me a fraction of what they did before. Contributors are powerless in my opinion, you have no way of influencing these sites. You also just have to trust them with their sales reports. From time to time I upload footage to all the sites that pay me, but while the number of shots I uploaded goes up, I only see my income decline year after year.
