Even if FB/Snapchat tries to make themselves more agreeable towards Asian markets, they still need to face the question from customer like this: if I have something (Line/Wechat/Kaokao Talk) that works great for me and my friends, what is the reason for me to use their western counterparts (FB/Snapchat)? Only because they are trying to make themselves similar to the local competitors ? That is not convincing enough.
