The comment about stickers makes me think you don't understand how much money they make and how much people use them. It's massive. Look at Line made 17 million from stickers in Q1 this year, Kakao made 311 million in revenue and I'm not sure the breakdown but stickers is significant enough that it's mentioned in with gaming as the main source of revenue. Stickers, whether it's reasonable or not, are a great way to monetize on messaging. Snapchat also allows you to find someone to talk to that no other service does as seamlessly. From my understanding anyway, people will send out snaps to a group of people, many time everyone they're connected to and after a few snaps back and forth with one or two of the responders, they'll switch to another channel and chat. One could argue adding messaging here would increase the stickiness, but I think snapchat is right in that adding it in would just be distracting.
