You don’t need Meta products to stay in touch with, especially Whatsapp. If they refuse to use Signal, just use RCS/SMS. Or if you live in European Union, you can use Balsio/Haiket/Arnacon, they are interoperable with Whatsapp. The disadvantage is that Balsio and Haiket work ONLY if downloaded from Google Play, while Arnacon works anyway.
