More like my ignorance. I don't own a PS3 so I'm really not intimately familiar with Sonys services. All I know is what's on the FAQ.
Neither Sony or Microsoft see any problem in charging for online services that are free anywhere from Twitter to Steam, nevermind charging a premium for digital content that is appropriately discounted on every other platform from phones to PCs, so my inclination to believe that they'd be game for another preposterous monetization of a normally free service is hardly picked out of thin air.
Fair enough, it's an old service, but that does nothing to explain why an upcoming streaming service, or open version of the existing service, would be left out of a FAQ where it might serve to quiet peoples concerns, or make them positive for the future.
That's hardly talking about reptillian humanoids or global zionist regimes, dude.
