I disagree with the authors premise that there can only be 2-3 behemoths. Has he not been paying attention to how kids use mobile apps these days? No one is locked in to a single ecosystem like they used to be.

People use gchat, Facebook, Instagram, snapchat, whatsapp, and iMessage simultaneously, for distinct purposes. And all of their friends do too.

As long as the app present value, kids these days have no problems switching back and forth between apps, meaning they can get hundreds of millions or billions of users too.

Facebook owns Instagram and WhatsApp. The only app on your list that isn't controlled by a giant company is Snapchat.
