Eww. Proprietary chat protocols. What's the point, it's just text with different UIs every time. Well, plus "stickers" or some overlay UI.

Now people around me are pushing WeChat like it's the hottest thing since the iPhone (actually, it's likely due to the fact that Whatsapp is paid on iOS, and the iOS users are butthurt from being left out).

Never mind that WeChat is developed by Tencent which makes QQ (which is a horrible, horrible piece of [censored] I had to deal with when I handled a Chinese client), which is also known to have a government backdoor.

This entire software ecosystem dealie really hurts cross-platform interop. Natch.
