If you currently use Hangouts for your Google Voice communication, there’s no need to change to the new apps, but you might want to try them out as we continue to bring new improvements.
W.T.F? Don't bring me into your internal office politics...
Then there's Allo because with all the above they made it too complicated to chat with someone or something. Also Duo, because video calling was completely missing from the offerings above (it wasn't).
Google: please just leave hangouts alone!
Also, regarding branding: even overlooking the shell-game Google is playing with regards to moving features around (SMS => Voice, SMS => Hangouts, SMS => ?), the branding was confusing from the outset:
- Google Chat (GChat) - Google Talk - Google Voice
These might as well be synonyms.
Google Talk is the original XMPP based chat system and was known informally as Gchat or Gtalk. There were web and desktop clients. Hangouts is the "new" proprietary messaging system from 2013. Google Talk and Hangouts are integrated at least for text messages but Hangouts adds lots of features like group video chat. Google Talk provides XMPP protocol access for federation and third-party clients.
Hangouts app on Android could do Hangouts, local SMS, and Google Voice SMS.
I find it interesting that there is less confusion about Apple Messages even though it was renamed from iChat to iMessages to Messages. The app also supports both SMS and iMessage protocol. In addition, iChat supported XMPP and third party clients until was shut down.
The reason people aren't confused is because Apple just renamed the app on people's iPhones but didn't screw anything up for them. They were never forced to switch from one app to another app, never had multiple apps that did roughly the same thing with competing standards, and they didn't migrate users from one platform to another losing data in the process.
I'll never trust a Google messaging app because of that mess, and frankly I'm getting increasingly frustrated with Gmail/Inbox too and will probably move off it soon.
For bonus confusion, the Google Messenger icon just says "Messenger" and is nearly indistinguishable from Facebook Messenger, a completely different system. Better keep track of which blue speech bubble is which.
