> Is that how Google ended up with eight chat apps

Its more because they killed their already working, well-accepted Google Chat app, not seeing gigantic profit or any market control benefit from it. Somehow they thought it was a better idea to have some 'chat' through the browser - which resulted in whatever 'Hangouts' was. Prioritized 'engineering' and profits over users as its so normal for large public corporations.

Then Slack and Discord came and wiped the floor with all of them.
