I have a couple of problems with the analysis. First, users don't use WhatsApp because they're concerned about Facebook hoovering up all the data. They use it because their slightly cooler social influencer friend uses it, so they think they should too. Regular users don't care about Facebook from a privacy angle - they obviously do if it's splashed across CNN, but they forget again the next day. Second, a factual error: > Facebook’s business model on the other hand is built on the idea that the more a user interacts with Facebook (or Facebook-connected sites and apps), the more Facebook can earn, because it can present more ads. Not more ads — _better_ ads. They already fill all their inventory. The difference is important. Better targeted ads annoy users less, but command a higher price from advertisers. And change 'giving them data' from a negative activity to a positive one! Right now, Facebook's in a weird place. They know loads about me, but their targeting is still really crap. I don't know why they don't just add a 5 minute "improve your ads" survey, where they ask outright which ads they should be showing me. I'd happily tell them the sorts of things I buy loads of, if they'd promise to only show me ads about those things. Anything to get rid of belly fat ads. If Facebook stored 10 times as much data about you, but the adverts were awesome and you wanted to buy every single thing, would you give them the extra data? HN users might not, but I think most people would.
