I did not consent to those companies knowing my phone number, name, and likely other information!
But you clicked a little button that they can so its completely fine! \s
That is likely my single biggest pet peeve of the current state of tech is other people being able to consent to MY information being gobbled up just because they clicked a damn button.
Germany and Switzerland have some exotic secure messengers that were quite popular (and may still be) like threema.
There was also some quite suprizing stuff. My inlaws were, until recently, using Viber. They didn’t know why (none of them are computer people). It was wild to me to discover a chat app I never heard off in a circle of people completely outside of tech.
Anyway, the only longterm solution is an open standard. Propably XMPP. Or email after all (it works, look at delta chat).
But to be fair, most consumers aren't going to care about an open standard directly; they'll care about finding and chatting with their friends. An open standard is a great way to get there when it works, but, for example, WhatApp being a de facto standard in much of the world accomplishes the same thing in those regions.
Google jumped on jabber years ago, then jumped off.
I guess. But it doesn't really explain why it continues to be so popular, to the extent that even on forums like this (where well-grounded skepticism of big tech companies like Facebook is generally taken for granted) you have Europeans acting like Americans are backwards fools for not wanting to jump into bed with Facebook.
Its simplicity, cross-platform (as people out there use Android more than iOS) and user base was and still is the big moat; there have been quite superior applications over the years, yet none of them are used as the main messenger except by some niche communities. Telegram has been there since 2013, it's quite popular because of the features but I doubt it will take over: WhatsApp is enough and everyone already knows it.

This map also only shows the most popular, but that doesn't mean it's the dominant messaging app in that country. It's very, very messy.
I'd rather not cite the below but where's smoke there's fire. This indicates Whatsapp has twice the active users of Messenger. https://www.statista.com/statistics/258749/most-popular-glob...
The problem is that given a random person off the street, how can you figure out which messenger apps you have in common? And assuming everyone outside the US uses WhatsApp like the grandparent poster I replied to did, doesn't work.
