This is not an exhaustive list, just stuff off the top of my head.
Finding/viewing/sharing/joining chats
Adding users (can't find them, invites not being received, etc)
Broken messaging (messages not arriving, formatting not being handled or handled the same way, even on the same XMPP server!)
OMEMO issues (key exchange not working, or OMEMO keys getting lost or something when both clients involved were working perfectly fine the day before - Telegram's E2E doesn't break randomly and no, there isn't a MitM issue)
Clients asking for encryption, but then get mad because you're using Thunderbird's XMPP implementation and complain they don't like the encryption supported by Thunderbird.
Not being able to disable encryption on some clients (I actually rather not have encryption anymore because of all the problems)
Multi-device messaging issues (fresh chats can have messages going to one device but not the one the user is active on or history synchronisation)
Mobile notifications inconsistently working, even when using external push messaging providers (it works consistently always on Telegram, it's even more consistent with Matrix, even though Matrix has more push disadvantages)
Client crashes (I can't even remember when Telegram last crashed, but Pidgin crashed on me today and it has only a single XMPP account on it)
Clients failing to connect without useful information (Siskin no longer connects to my account and the only indication is that the "enabled" button becomes disabled, despite the account working on other clients and devices)
UI lockups (Miranda NG, Psi, Gajim, and Pidgin all tend to become unresponsive for short periods of time, probably a blocking wait being imposed in the UI for some reason?)
Common issues that every modern messaging application has, like voice and video, are barely supported overall despite being fully supported in the XMPP standards (file sending is even an issue for Thunderbird)
There is next to no failure recovery on most XMPP clients. Anything that fails on Telegram will try to recover and resend without needing the user to intervene and helpfully displays it's working on it.
I understand. I don't mean any disrespect, but the few tickets I raised, including crash-related ones, are still in submitted status, awaiting developer replies from many years ago. I'll reconsider putting in tickets again, but understand my frustration.
Look into SimpleX Chat. It's like Telegram but with trustworthy encryption that's always-on, multiple profiles, and the servers are interchangeable so if one or two go down you can just switch them out.
Evgeny is a venture capitalist (ew) but the product is solid and they've published two TrailOfBits audits with a third completed and awaiting publication by TOB
Yeah, I've been writing software that provides feeds for RSS, but I exclusively use Atom. It's just a better format. It does create ambiguity when using a site like this because I'm not sure if my sites will qualify as having an RSS 2.0 feed or not.
Why is this comment downvoted? It is factually correct. The reason why Ukraine has such an upper hand in the last 3-6 months with mid- to long-range drones is access to Starlink, even within Russian territory. Russia does not have the same, so it is harder to navigate their one way attack drones.
You can thank Marc Andreessen whose world view is apparently limited solely to "Snowden is a traitor". Thank god someone like him has fuck you money and can shape the world to his desires
(And I've heard he stole Mosaic code, which I don't know if it's true but would be consistent)
The local fiber guy goes out of business... you still have the fiber line there.
Its investment, not subscription.
