OK, Google Talk was a dead man walking for some time now. Even if it's not a nice decision for open standards at least they made a final decision whether they are either improving it or killing it. However, Google have completely lost their mind with messengers. GTalk, Hangouts, Messages, Messenger, Allo, Duo, Chat, Meet. Some available only on mobile. Some supporting SMS, some working only with SMS. Allo having G assistant in chat, G assistant is only with voice on their pixel phone. The tipping point was when both Hangouts and Messages competed to handle my SMS messages and when Hangouts won because of Gmail integration, they removed SMS from it. They really need to get it together.
