Kelly gets markedly uncomfortable when asked about royalty cuts (watch his fidgetting and hand movement increase during this segment). Then he answers by saying that "royalties don`t matter as much as the total amount of money we can make for our photographers and I think we`re doing a better job than anyone else with the total amount we pay out in royalties far exceeds our competitors..."
I read this as: iStock can take a larger share of your pie because you suckas can`t get more net dollars elsewhere. So even if iStock promised in writing that commission levels would be grandfathered, we will not honor our promise to you because we think that we can get away with taking more of your hard earned revenue.
I stopped being exclusive because of this and have found that I am getting more net dollars than before.
