I used Hangouts for a while and had a bunch of contacts on it when it was Android's default SMS app. Many of them were not particularly technical, including one of my parents whom I don't recall telling to use it. If you were using an Android phone, you were probably already logged in to a Google account. iPhone users had to work a little harder for it (install the app and remember the password to the Gmail account they probably already had).
I don't recall the UX on the mobile client having extra complexity over other messaging apps if I didn't go digging in the settings, but it's been a while.
There are many people I run across who bypassed the whole Gmail and Google Workspace ecosystems and have rolled along merrily with me.com and other email providers.
It's not a given that users will have bothered to register for a Google account unless they grew up in the Bay Area after a certain time period.
Wind back the clock to when Google tried to roll out Hangouts and the Gmail penetration rate was even lower among the non-Android users out there.
This is all anecdotal of course. Maybe it wouldn't have worked, but how quickly they gave up was weird.
Hangouts UX sucked big time. I remember lots of frustrating sessions with my parents about why video calls weren't going through, or how can some random family member join our family thread when they don't have a Gmail account etc.
You definitely had a rougher experience with it than I did, but my main point is Google launched it, didn't seriously iterate on it, and gave up its strongest distribution channel at the first sign of pressure from carriers. Since they keep launching messaging products, I must conclude they want to be in that space and it was foolish of them to squander their best opportunity.
Funny because now it doesn't. It routinely fails to surface emails that exist.
couldn’t believe they had fallen for an April fools.
But that was a limited time window when gmail massively outweighed the 10-20mbit of things like hotmail with effectively unlimited storage.
Sure. But is it the same Google account that your relatives email you on, or a different one that only that phone is using? When you drop this phone are you going to sign into that same Google account or make a new one? The answers for non-technical users are non-obvious.
But then again I would likely opt out of Hangouts, so it’s not a problem.
(And to be honest, things were working much smoother for me when I was on microG [0].)

Whereas Whatsapp was simple - only phone numbers to sign up, only text and images, only mobile phones. That simplicity meant my parents could onboard smoothly and operate it without having to navigate a maze of UX. I literally saw Whatsapp winning in real time vs Hangouts and other alternatives.
