Viber's Acquisition by Rakuten: Registered != Active Users

Last week, Viber's business model was revealed. It wasn't about stickers, subscriptions or PSTN dialing. It was just a simple exit strategy.
OTT. Over The Top. And in this case, instant messaging clients – are of interest to me.
I presented over a year ago about OTT players and their business models. It had 4 such models:
- Advertising
- Connectivity to PSTN
- Value added services
- Cashing out upon acquisition
- Rakuten paid $3.2 USD per registered user; or $9 USD per monthly active user. The difference between the two is huge
- Registered users is interesting, but irrelevant at best. If anyone pays up, it is for monthly active users – that's the immediate potential
- I am a registered user on Viber, but not an active one. And my registration? It is for my previous mobile phone number. Useless

- OTT vendors are distinctly smaller than they seem
- If someone talks about registered users, then the question is where is all of his activity
- The large players are WeChat and WhatsApp. The rest are playing catch-up
- WeChat and WhatsApp have VERY different approaches and business models. It will be interesting to see which one will stick in the long term
