So, Facebook is going to try and parse your WhatsApp messages to determine your relationship status, instead of using the Facebook relationship status field?

When's the last time you messaged a friend for dinner that night, then checked Facebook, and even read an advertisement?

Tax advertisements are just going to appear for everyone of age, when it's close to file them. The message doesn't bring anything new to the table, since everyone is talking about taxes.

Why is Google scared? You do realize the vast majority of the internet is running Google Analytics, so they know what you search, and what you visit. Did you check that menu for the Indian Bistro on your phone? Google knows, and they'll start showing you other restaurant advertisements. Price a new BMW on your laptop? Hmm, why don't you look at some ads for a similar Audi in that price range? Google has a disgusting amount of data for individuals.

Anyway, I'm getting off topic, Facebook didn't buy WhatsApp for 16B to slightly increase Facebook advertisement targeting. That idea is absurd. They want more control over those 400,000,000 users and they want insurance that WhatsApp doesn't further enter their territory.
