Because it Just Works(tm) and there's no fiddling or faffing about necessary.
That's what marketing would have you believe. For example Hangouts broke the ecosystem horrible, and now xmpp and hangout users can no longer intercommunicate (and wonder why their messages are silently dropped).
Users complain that they need 6+ apps to keep in touch with friends.
The real answer, IMHO is "Because they market it as 'just works'.".
