The problem now is that PC uses the same network as console but get it for free.I always have mixed feelings about Gold/Plus. It's felt egregious next to 'free' multiplayer on PC or Steam. Live was a significant leader in how multiplayer should work though.
I don't usually play multiplayer these days, so not really sure what the modern landscape looks like.
Same voice chat, multiplayer network etc.
In the past was easy to see why paid for 'network' features as was a leader as you say.
I know I'm talking about a single dollar difference, but I think this was an opportunity to take a big step towards on the surface bringing a level of parity/fairness.
