I don't really believe WhatsApp was bought to show ads on WhatsApp, I believe it was bought to forestall competition and protect Facebook's existing revenue. Zuckerberg was afraid that users would leave Facebook for WhatsApp, and tried to prevent that by buying it and merging it in to messenger. They largely failed though, as for political (and maybe also technical) reasons the merge was cancelled.
