The Sony PS4 launched in China and was not region locked, yes it had some limitations like it cant download foreign games or log into foreign PSN accounts, but it can play foreign PS4 game discs, connect to foreign servers, add friends from anywhere on the globe, and download patches for games from overseas. Similarly, the global version of the console will allow players to log in to Chinese PSN accounts, play Chinese PSN games on disc, and download patches from the Chinese PSN servers.
Where as with Xbox One the console launched completely locked, you can only use China account, only play Chinese disc and download games, not connect to any foreign servers or friends outside China etc....
So what happened is PS4 launched, then shortly after Microsoft unlocked the Xbox One to make it region free like PS4. Of course this is a good thing, however Chinese on social media reacted negatively because they didn't understand why Microsoft didn't just unlock the console from the beginning like Sony did. Which is a valid point, and so some distrust between consumers and Microsoft has started.
