If you don't like open platforms, don't buy into an open platform? That is kinda why consoles are popular.
But if that's your biggest problem, you'll surely like what Epic are doing? Integrating Uplay, MS store and so on features, friends/online lists, sharing the same network infrastructure ect, for any companies that agrees to share it with them. Anything that works on Steam but has seperate networking for other stores is almost certainly because of Steam's multiplayer APIs not being portable or open.
And THAT to me is more anti consumerism than exclusivity deals on an given launcher providing they allow "lets call it cross launcher" multiplayer.
