Yep. I doubt many people will care about this in 2017. The network effect they had 10 or even 5 years ago would have been a great sell, but you can get the same thing for free now, and all of your friends are probably already on one or more of the alternative services. Entering the market when WhatsApp / Line / WeChat / Telegram / Viber / Kik / Kakao / Weibo / Facebook Messenger / iMessage exist seems like a bad idea.
