They implemented Google Talk, which was fantastic and opened it up to the world with XMPP support, again, fantastic. Implemented Jabber federation which again was great. One of Google's stated goals was interoperability[1]. Because of this a lot of people moved from running their own Jabber servers to Gtalk. Google then started to add non-standard extensions[2] and in 2014 dropped all interoperability in favour of Google Hangouts integration, meaning that with a Gtalk account you could no longer talk to Jabber accounts. If this was Microsoft, the term that would be used would be Embrace, Extend, Extinguish, but it's probably more along th lines of team reorgs and changes in strategy. Google claimed trouble with spam XMPP federation, but this[3] article sums up some of the feelings at the time, and it's more likely that with a bunch of different products Google needed to consolidate efforts and the new team had different prioritie (like hangouts and wave at the time).
