I would have faith in the survival of facebook if whatsapp and Instagram stay with their own brands, but this move seems suicidal in sullying them with the Facebook name.
I don't know about others, but I would rather Instagram stay separate to facebook. I know it's only messaging, but it's a step in that direction.
This reminds me of when AIM/ICQ merged. Now they’re both gone, right?
AOL sold off ICQ about a decade ago. To mail.ru. I think they're still going. Fairly sure AIM is as dead as MSN.
When I first started going to Chine, after marrying my wife in 2002, everyone there that had a computer used MSN Messenger.
