The most interesting part to me wasn't the technical details but rather the MAU, WAU, DAU stats at the end from random sample. Way fewer people than I would have expected use WhatsApp on a weekly basis.

This is in France, where text messages were free (unlimited with your subscription) long ago before we had internet on our smartphone. Thus people use text message a lot and did use WhatsApp only to contact people outside from France
Text messages were around €0.10 for most plans until 2012 though (due to the unlawful collusion of telcos).
Not in France actually, we mainly use WhatsApp as a main message app; nobody uses SMS nowadays
Well I do use SMS, as well as my friends and family in France.

I use WhatsApp with Belgians (I live in Belgium) because SMS's are not free for them, and also for sharing photos because MMS is a mess.

true, my point is more about the tendency of using groups of people to quickly share. Which SMS does not do properly.
