Google’s strategy around its consumer messaging services remains baffling, especially since it killed off Allo (yet kept Duo on life support). Today, the company clarified the timeline of the transition from classic Hangouts to Chat and Meet for its paying G Suite customers. For them, the Hangouts retirement party will start in October of this year.

For consumers, the situation remains unclear, but Google says there will be free versions of Chat and Meet that will become available “following the transition of G Suite customers.” As of now, there is no timeline, so for all we know, Hangouts will remain up and running into 2020.
