Sometimes I'm just glad that I don't even like online gaming.
I'm immune to these rumors!
Don't be too sure. I'm in the same boat, but these still scare me. Right now, demos and some purchases are locked behind that paywall for a limited time. I've never understood that. How can they not want my money? How can they not want me to try their interactive ad?
But anyway, I can totally see them locking demos to subscribers only, or even having Gold exclusive games. I wouldn't give it a high chance of happening, but who knows? And there's always the fast servers for subscribers, slow servers for peasants, etc.
In other words, not playing online does not necessarily make you immune. The only thing that would do that is not being online.
