WeChat is definitely popular but it isn't everything.

Chinese users also buy apps, take photos, watch movies, listen to music, create content. All of which on iOS is tied to the Apple services ecosystem and hence the switching costs are still significant.

I agree with buy apps, but not the rest. There are lots of local content providers, like Tencent Music, Tecent Video, iQiyi, Netease Music, Youku, which provides music/video streaming service with much better localized content.
