Just send sms? Like video calls, custom emojis, reactions, groups, business accounts with online catalog and checkout process, channels, custom status, etc all that with sms? Come on now, get real.

Maybe telegram or signal if you're going to propose an alternative but sms is ridiculous.

It's uncommon in the US, iMessage and SMS/MMS/RCS are the primary text chat systems here that everyone uses from their phones.

I meant out the US

I don't use it at all. The only Meta app I do use is Instagram and I'm rarely on there to be honest. Don't use Tik-Tok either, FWIW.

TLDR: Yes

Just because everyone you know uses it, doesn't mean they can't use something else with you, maybe even understand for themselves why they shouldn't use Meta.

And it's very easy to do: you make a message for everyone you have as contact and tell them that whoever wants to continue to talk with you can continue doing so on signal, simplex, matrix, or whatever, explaining why you made this decision(meta bad, blah, blah) and tell them that in one month you'll delete your meta account(s).

At the end of that month, you do it. Remove any trace and very important: DON'T GO BACK on your decision(1 week, 1 month, 1 year) after. Whoever wants to talk, will do so wherever you told them to find you. Those that don't, well... they won't. And you'll also find out who actually cares enough to talk with you.

Talking from experience.

Absolutely. No accounts on Meta properties ever. My primary form of communication is actually the phone, followed by email. Have you tried actually calling people?

I don't use any WhatsApp. I also don't use any Meta products. I don't give a fuck who else is on them.
