No offense but, the only person you're allowed to be pissed at is yourself for buying into a completely unproven subscription program. Same reason I blame only myself for buying the machine when it was $600 only to have two of the same models fail on me.
I love my PS3: I own nearly 80 disc-based games for it, 50+ PSN titles, and have no shortage of disposable income, but I still refuse to pay those dickheads for "PS Plus" until they get their heads out of their asses and actually offer something worth paying for. Right now all they're shilling is discounts on PSN titles that most gamers already own or have decided they're not interested in, and game trials for titles that are years old. You want free game trials? Go buy a used copy from GameStop and return it within 7 days for a full refund; but, for God's sake, don't pay SONY $50 a year to do it...
Right now, PS Plus is garbage, and only serves as an embarrassment to SONY, especially when its closest competitor (LIVE) offers so much more for a slightly higher price. When I saw that nearly 50% of the people on my Friends List signed up for Plus during the first month, it made me want to vomit out of a combination of disgust and pity.
