Playstation Plus does not have anything to do with hacking on the PS3 and is a Playstation Network premium service
The free PlayStation plus games say they are only valid as long as you are a PlayStation Plus Member. Games you purchases including the two free downloads for customer appreciation are yours to keep. The games you get to keep also includes the games that were discounted for PlayStation Plus members. What I figured was that PlayStation was just getting started with the customer appreciation and it would be through PlayStation Plus that additional offers were made. It might be wise to purchase an additional 3 or 12 month subscription to PlayStation Plus. I have not yet done so because it is subject to automatic renewal and if you do not have money in your wallet it will charge your credit card. Since the system just came up yesterday for me I have not investigated how to cancel PlayStation Plus once purchased.
