An instant messaging service has never made any company money. Ever.  See AIM, see ICQ, see MSNmessenger, see Jabber, see Google Hangouts or chat or whatever, see that Yahoo one no one remembers.  They're too easy to code and implement. If you try to charge, people just leave for a free one.  If you get too annoying, people just leave for another free one.
