> Have you never heard of network effect ? Having one the size of WhatsApp is absolutely a unique value proposition since it is impossible to replicate due to acquisition costs.

Yup. It's totally possible to replicate the "value proposition" of a network-effect-exploiting service - the easiest way is to just wait a single generation. Younger people tend to avoid things their parents use; it's a problem that Facebook is starting to have right now.
