alt Hacker NewsGood luck trying to not use Meta products (specifically WhatsApp) as a (non-tech) professional outside the US needing to communicate with their counterparts.
The best compromise for such people, I guess, would be a work phone number that's solely for business WhatsApp communication.
I don't think it would be difficult to explain, especially in a professional capacity, that you don't use Whatsapp or Facebook because it does not meet your privacy requirements of your business.
