Basically : They design for value for users instead of, and they add features relentlessly instead of hitting product-market fit and stopping development until a competitor comes out with something good (looking at FB).
This is probably due to the high level of competition and limited marketshare the firms in China are looking at. FB and Western firms want to rule the world, because they can, so they are still focusing on growth with iniciatives like internet.org. Chinese firms know their market is China, and they understand China, and it will be hard for them to export, so when they grow as big as WeChat the options are more limited.
Their option was to build a whole ecosystem around it that could capture maximum user value. They also seem to prize their users religiously, which is great for them. But it might not have happened for them that way either if they were hopeful of capturing the entire world.
