I see a few claims of spyware in here. Not that I doubt you, but where can I find out more?
So the basics of what I've read is:
I know its different now because Discord has nitro and there are lots if good reasons to subscribe. But Discord ran without all if that subscriber funding and in that time they probably found ways to make money off of what resources they had at the time... Information.
I mean, how else do you think they can make it so all your existing chats show up when you log into your account from a different device? Signal stores all your messages and media as well, the difference is they encrypt it on their servers. Discord doesn't.
That's more problematic, and there should honestly be a law against that. Come to think of it, doesn't that violate the GRDP? Either they have to treat their EU customers differently when it comes to this, or there's a lawsuit waiting to happen. In the former case, you might be able to force them to delete your data by using a VPN to pretend you're in Europe.
> Signal stores all your messages and media as well, the difference is they encrypt it on their servers.
What evidence do you have to support this claim?
The last time I looked into this, messages and media were only stored encrypted on servers until they were retrieved or expired.
After that, the local device is where things are stored.

How do they manage to make the same messages appear on multiple devices? I use Signal on my phone and two other computers. Even if one of them is offline, once I go online, it will show the same messages as the other devices, even if I have already seen them on my phone. They sure aren't going to connect to my phone to pull the messages from there.
I do think there is a limit to this feature – when you connect a new device, you will not see any history on there. Only messages you receive after activating the device will show up, so it's possible they just keep track of how many active devices you have, and once a message has been retrieved by all of them, it will be deleted from the server. But that would also mean that if you don't sign out of a device before retiring it, messages COULD potentially stay on their servers forever, unless they delete them after a certain period.
> How do they manage to make the same messages appear on multiple devices?
For a long time, they didn't.
I don't know for sure, but I expect it involves keys that multiple devices share. Any "linked" device would be able to download the encrypted copy and decrypt the message that way. Once any device has done that, it can send a copy to any other devices using the unique keys it knows for that device.

Right, that makes sense, although the article doesn’t go into detail about how the server decides when it’s time to delete a message.
It also doesn’t back up your claim that multiple devices sharing the same account will ever exchange messages amongst each other. Which would be a technical nightmare BTW since they could be located behind firewalls etc. and this still require a central server to coordinate. Might as well keep the middle man in that case and leave the messages on the server until they’ve been retrieved.
My initial point therefore is mostly correct: messages ARE stored on their servers in encrypted form for an unknown length of time, although likely not forever.
