your argument boils down to "the fully functional and loaded gun is in this weirdo's holster and he won't use it".
the whole point is not relying on the benevolence of the weirdos out there and not letting them even be in the position to do any harm. encrypt my 1on1 comms and I don't give a fuck what happens in the pedo/terror/carding/etc public groups. ample time to implement that in the past decade+ and be on par with practically every messenger out there. but he/they won't implement it, they insist on all your shit being in the "cloud", in plaintext, forever. there is no scenario where there's not a malicious intent behind that.
I've been using Telegram since the early days. it was phenomenal vs the crap of its day - magical, even. like many, I was enamored with the vision of durov the folksy hero battling the forces of evil (in a bozo nightmare) and bequeathing us this tech marvel.
but I can't trust it with anything any more. if weirdo can't be trusted about some stuff, then he can't be trusted with anything. enough for me, YMMV.
appreciate the effort, but kinda went overboard with the deets :) I run several prosody XMPP servers so I'm familiar with the underlying tech. what you describe should be feasible with it as well, but there are constant issues with devices not being able to access history, so I was wondering if things were better on your end.
so, based on this, I'll spin up a snikker docker and try it out for a coupla weeks, see what's what. many thanks.
edit: turns out this snikket thing is conversations (standard XMPP client) and prosody (XMPP server) with different branding.
