How am I supposed to message people when the only messaging app they use is whatsapp and facebook messenger (which I don’t use)?

I guess the only easy alternative is to use SMS and email since everyone use it. But it is not safe.

I am always open to alternatives like Signal, Element,etc. But no one use them. I am not going to force people to use a messaging app.

Thanks. May I ask what is so cool about the instance that I am on? ;)

Whatsapp. Everyone in India uses it. Its like the imessage situation in the US. So widespread.

Schools, college, friend groups, family groups all are on whatsapp.

A lot of schools and colleges in Kerala (Indian State) use Ubuntu. Kids are taught how to use software like GIMP and Audacity in schools. It has become part of the syllabus in public schools.

12 th standard students have to do maths practical in GeoGebra.
