In Europe WhatsApp was huge well before Facebook purchased them. From my own experience, the product has barely changed since then, so I don't really feel like it's a Facebook product (yet), and so while I dislike using Facebook services WhatApp is basically fine for now.
Almost everyone I know uses WhatsApp. Funnily enough my family are the only ones who don't, and use iMessage instead. This isn't an active choice though, it's that they are on an iPhone and using SMS, so they get iMessage by default.
This is a long way of saying that for many Europeans, "Just use WhatsApp" feels like an obvious response, why wouldn't you?
