Regularly, I use the following for near-realtime communications ("text messages”).

- SMS/RCS/iMessage (friends, family)
- Facebook Messenger (friends, family)
- What's App (friends)
- ActivityPub/Mastodon (friends)
- Matrix (friends, work)
- Discord (work)
- Mattermost (friends, locals)

I'm sure I'm missing some.

The fact that no one is allowed to make a single piece of software (for wide distribution) that talks on all of these systems is the kind of garbage @pluralistic often talks about.

My wife must use Teams to communicate with her mother in a nursing home.

It's not actually working properly, and other things would (and did), which also frustrates the staff on the other end. They are not permitted to use things that actually work as intended.
