I can't trust sony with a home address, let alone a credit card number...and even if I could, I would feel bad about Sony getting a cut of the money, which they use to pay lawyers that harass innocent Linux developers while ignoring the people working on piracy...so PSN cards are out of the question; I might as well donate to the KKK or some terrorists or something.
I don't feel bad for the developers either...DLCs for disk games could be done easier and safer through in-game activation codes instead of the PSN store. Not only that, but they wouldn't have to give sony a cut, a PSN crash would not affect them, and if there was a breach, it would be much smaller. As for download-only, any developer that releases a game as download-only on a single platform clearly isn't interested in getting a lot of customers to begin with...even before the network went down, there were a lot of people who never visited the PSN store anyway.
As for the free games, they are all ancient download games...Sony claimed that they worked long and hard to provide a list of disk games and not the typical Sony store BS...and then they gave us a list of typical Sony store BS, all old games that were already in the PSN store, and which are either already owned or simply unwanted by 99% of the community. If someone chooses to play these games instead of the new games, then the new games didn't deserve to sell in the first place; there are games from the Sega Genesis that I would rather have...and that is in spite of the fact that I own the "Sonic Ultimate Genesis Collection".
