I read the article before I reacted but this is a bad move for a lot of reasons:
* user hostility & just doing this with messenger app.
* messenger app exists as does instagram and whatsapp. You want your own ecosystem, build a phone or an OS
* overplaying their hand. facebook is successful because it is a defacto standard. However, fragmenting new users by expecting them to have 4 apps (whatsapp, instagram, messenger & moments) as well as a website is a lot to ask. especially on a phone thats core function is messeging and photography, they are either launching an OS or they are insane.
Now, I use facebook occasionally out of convenience but I am not a huge fan of it. I recognize I am a fringe & atypical user concerned with privacy & tech consolidation, but threatening teenagers wasn't a great strategy when I was one not that long ago, so the alternative to "if you live under my house, you fol my rules", is to crash with your mates apple, microsoft, google, twitter, snapchat and whatever else exists
