From what I've heard the publisher can pull their games off of psn or any download service or, to some extent, change the price as well. I have seen this on psn and xbl a few times already. Why they would pull their game, I couldn't tell you but it does suck. I was recently considering purchasing mx vs atv but was waiting to finish another game and two days later when i went to get it the price was increased from 9.99 to 19.99. Needless to say i didn't buy it out of principle. Yes it is their product and i believe they can do wht they want be it just doen't make sence to do that unless there is some kind of charge from Sony to allow content to be put on their service.
