Honestly, I don't mind. I am just happy I can remotely deactivate all PS3's on a computer. Plus, I only have 1 PS3 but I guess it's hard for those who actually own more than 2 PS3's. I guess the limitations is to stop people from abusing. Blame those people who abuse it and not Sony.
There are other ways to do that. It's part Sony's fault for not coming up with a better solution. A multi-million dollar company should be able to come up with a better idea. They could do what Microsoft does and just ban people who abuse and or hack and do it on Xbox Live. I don't do anything like that so the threat of a ban is nothing to me. I'd rather Sony do that.
