Why Jami isn't considered as WhatsApp alternative?
Jami is p2p, it just cuts the middleman. Is it bad concept? I haven't had the chance to test Jami or Signal, no adoption from my contacts. But, as from a federation and anti centralized services, Jami should be the better alternative, right?
I had never heard of it prior to your post. Looks interesting, but it will be hard to get enough people to use it. It took years for most of my contacts to make the move from Whatsapp to Signal.
It took me about a decade to get people I needed to contact just onto WhatsApp from fbmessanger so I could delete Facebook. I'm never going to get people to move to a new messaging app.
I managed to get my immediate family (and my sister's husband) onto Threema, the extended family is on Whatsapp with zero chance of switching away.
On the other hand, one cousin's husband can't stop spamming the group chat with pics of their daughters. Not just "special event, here's a pic of each at their best" or whatever, but multiple. fotos. daily., sometimes videos too... As a consequence, I've permanently muted that whatsapp group and only occasionally take a peek at it.
