That is disappointing, but having read the statement by AoN I kinda understand why.
Paizo is having financial troubles, mostly due to things not their fault. The AoN partnership has brought them zero dollars over the last eight years of the partnership.
If I were Paizo, I'd now be looking at either partnering with somebody who could bring in some money, or setting up my own version that I had a plan to monetize.
Since Paizo is encouraging AoN to continue what they are doing under the community use policy, this isn't something that will break AoN. My guess is that Paizo is going to announce a paid something or other that offers what AoN is losing out on, namely release day rules updates.
