A lot of this overreaction reminds me of when Facebook bought WhatsApp. All the alternatives came up for a few weeks/months, but the dust settled and not that many left in the end. Maybe it’s different this time? But the cycle feels the same
Now, many of the people I meet are fine starting a signal chat instead of SMS.
To be clear, it's still not enough to start a group chat with random people because of course that's a problem in 2022.
You don't always get to pick the venue.
Twitter has a "culture" in a way that whatsapp doesn't really. That's a lot more ephemeral and subject to disruption.
