most people see messaging apps like Signal, WhatsApp and other third party apps for personal use only.
In Europe, businesses, especially small businesses often use WhatsApp, to the point of putting its logo next to their phone number on signs. I wonder what creates the perception where you are that messaging apps are for personal use, not business.
It seems like at least some people view apps that come preinstalled on their phone differently from other apps, but I’m not sure why.
