I don't agree with it, but the reasoning goes like this: It makes sense for both parties because for the seller the investment gains from the capital they're getting from this transaction will be similar to what they're making from running the registry. But they no longer have the headaches of running the registry. For the buyer, well, it's a monopoly so the sky is the limit. Even if current seller is able to raise the prices, they might not want it due to the backlash this would cause. Current buyer is less constrained by this.
