The biggest one for most people would be large files since you can't really do that on WhatsApp. WhatsApp images and video also get deleted after some time where as telegram don't
It's a really simple matter of practicality. I can either use whatsapp and talk to people or I can install telegram and send messages into the void, because no one fucking uses it.
well thats fine ofcourse ...making all previous pro whatsapp arguments kinda invalid.
"i wanna chat.but only with my bubble. because we are right. has always been lile that. why dont i understand what the kids say these days? why am i being ignored in the workplace? was i stubborn? i am a dinosaur? why am i so alone? why do my grandkids hate my point of view?"
and so on....
