I can’t even get people to USE telegram, which they have already installed, let alone get them to understand, subscribe and install a federated messaging app. it seems like it’s whatsapp or back to the trained pigeons.
Nobody should use Telegram, in my opinion. It's run by a shady company that doesn't even disclose the inner workings of their service properly, uses a non-standard encryption protocol and doesn't even encrypt chats by default. The only thing I like about Telegram is the fact that you don't have to expose your phone number to use it.
One thing they really have going for them is timely delivery of image data.
When I detect motion in my driveway I send them the JPEG through their API, without skipping a beat I get the image on all of my devices including my watch.
I tried email, discord, SMS, slack, pushbullet. Stuff either takes a long time to come through or comes through missing an image. I honestly hope they never shut down the service because I cannot find another service that runs as well. Fortunately for my needs I don't care and the least about encryption.
I got a small team in school to all adopt my self hosted Matrix as a chat solution for a project we were working on throughout the year. It was great. Everyone jumped back to Discord after we graduated though.
Yeah it's definitely a chore to get anyone to use anything other than iMessage. A few friends and I use Signal even though they have iMessage and loved it. But everyone else is hooked to iMessage. Convenience is King in terms of adoption, unfortunately.
Even if the messages are end to end encrypted I wouldn't trust a third party with that data (unless it was a company that does it for a living.)
I'd probably recommend running your own instance, I imagine for that few users it would be pretty cheap. Though maintenance is probably the biggest issue there.
Or just use a third party Matrix server but send client info over email using GPG keys. That would cost you nothing.
Thank you. I think in my (ill-educated, poorly framed) original question, I think I was seeing if there were recommendations from the list on joinmatrix.org/servers/ I see that some are green-lit for privacy while others aren't.
This team isn't enterprise level or anything and I'm just looking to elevate them from emails to, originally, Slack. They're not sharing state secrets or anything, but are inconsistent about sharing client information that while not necessarily directly identifiable, should be kept under a tighter lid than it currently is.
