What do you think why Viber, WhatsApp, skype, WeChat, Snapchat, IMO, Line have not yet launched their crypto platform?
But Kik and Telegram did it.
After all, companies can get 2 huge pluses:
1) to collect a large amount of money for ICO
2) add hype to marketing and popularity among users.

I think because they are already popular and they don't need to use some fund for that because they have the sure and they have their own strategy to market their apps. As I see, upcoming project will be on ICO to promote it also to have a potential investor who believe on their project.
This will cause a negative feedback on their end to add up. We all know people don't like no ads on their stuff. And offering cryptocurrency based on their favorite apps will make the user feel like the people behind this is trying to rip them off of money. Aside from that, cryptocurrencies are no get rich schemes, they wouldn't want to take the risk of getting a separate department on their team that will handle the crypto business.
