As always test test test and then send traffic to the best converting for your traffic. For 7+ years I have been doing just that. These changes just mean more testing
It also means the playing field is flattening, at least till the next trick of billing is brought into the light. Hey at least mastercard and visa have not just said we wont process for adult anymore. Though I do expect that at some point in the next few years. And if you think they cant or wont turn off adult, it will be a big surprise for you when they do. Instead of bashing people for lowering payouts, just test to see if at the new lower payout you are making more money with them than the next program. If you are stay with them, if your not move on to the next program. I can not tell you how many times over the years I have switched back to sponsors after they changed things around a bit. Nothing has changed its buisness as usual. We will be keeping our payouts the same, but then again we have a much different business model, than recurring billing.
