I guess it more or less about the fact that PS+ is going to be an upgrade to Sony's online gaming rather than just extra benifits, but at the same time its not going to lock up features that had always been available to PS3 users prior to PS+'s creation. Xbox One will continue to be restrictive on content that is already free (or you already have a subscription for) in other places as a crutch to hand over your $60 a year.
As I had always been an XBLG member, I didn't know netflix didnt work without it until a few months ago when a friend acquired a 360 and couldn't access netflix. No one is going to pay an extra $60 on top of their $9 a month to watch netflix. Its pretty silly of MS. The only thing that should be XBLG required is online gaming and features that are exclusive to X1.
