If Telegram have E2EE by default, it won't have fully synced history. This would be much less useful.

Could you explain why you think that would be the case?

Well It isn't necessarily impossible, but Multi-Device encryption can get complicated.

It all depends on how things are done, one way to approach e2e with multiple devices is, each device gets it's own key, and the sender encrypts the text to all the keys. (Or usually uses a symmetric session key, that is encrypted and sent). However what do you do when a new device joins in? Someone needs to rekey all the messages for the new device.

Another way to approach this might be share the encryption keys across all devices, and make adding a new device basically sharing that key. This obviously comes with it's own set of disadvantages.

And in the end, what do you do if someone loses all their devices? The encryption keys are just lost.

I guess telegram just doesn't want to deal with that, which is kinda sad since it's a really good app and multi device encryption support would just sell me on the app.

> There simply isn't any encryption besides SSL for all the rest, which at one point they were boasting is the cause for their generally excellent performance (no distribution of keys etc). They didn't change that unless they ware uncharacteristically quiet about such a major new feature. It would run counter to their motivation for not doing it in that earlier blogpost. It also doesn't make sense to then have MTprot…

Please project elsewhere.

The search function could not be done server side and would be trash. See Keybase.

When I want to look up what I said to someone 5 years ago, fast search is priceless.

That is only true for the End 2 End encrypted chats, which are a separate and not very user friendly thing. Regular chats and group chats/channels are by design unencrypted.

It is false. Click the link to the FAQ. The paragraph for the quote begins with "To protect the data that is not covered by end-to-end encryption"

Sure, they're encrypted with a key that they have.

They have complete access to the data.

>Privacy, encryption, tracking etc. I don't care about. All the messengers suck in this perspective.. How is Signal not far better, here?

You need to give away your contacts in order to chat with anyone.

> you can set up your own matrix server Synapse is still one of the worst installation processes[1] I've gone through. I'm extremely comfortable with Ansible and Docker but their install process sucks if you aren't exposing your Matrix instance to the world and don't have a domain pointing at it. On top of that, there are so many moving pieces to it if you want to bridge it to other services. I got it all installed b…

There is Dendrite, a complete rewrite of Synapse in Golang by the same authors https://github.com/matrix-org/dendrite

Oh, that's awesome! I didn't even know this existed, thanks for the share.

I think the bigger question is anti-spam in anonymous chatrooms, even with the mobile phone requirements spammers (in particular from Nigeria, why does this country have so many scammers in particular?) are everywhere and spamming all the time, I'm in 5 or so groups and every day 2-3 spam messages have to be deleted. There are millions of fake channels and I wouldn't be surprised if up to or over 10% of telegrams mes…

I would say it's the same question as "what does IRC do?" as the general design is the same - maybe a bit more friction signing up with Matrix than IRC but at the end of the road they operate on the same trust model. The Matrix team blogged about a spambot attack last year on this very question: https://matrix.org/blog/2021/06/30/security-update-synapse-1...

Ah sorry that's a spambot attack, the spam on telegram is 99% Indian/Nigerian origin of people literally just signing up to go into group channels and spam whatsapp channels/msg me for how to make riches/join this trading signals channel you'll make millions.

If you're lucky they'll personally message you with something like 'hey' and then wait for you to respond, initiate a convo and try and get you to fall for their classic HYIP: https://en.wikipedia.org/wiki/High-yield_investment_program

Searching for Ban on a random group channel this is how common it is: https://imgur.com/kOtilgL

It's not worse, aside from chats being unencrypted by default. I've had suggestions on Instagram of people who I never got in touch with, only because my wife, who has no FB account, is in the same WhatsApp group as these people. They mixed in a bunch of other "you may know" people to make it less obvious, but when comparing her groupchat and my suggestions, it's clear they made links via IPs and phone numbers. At le…

To me a chat app not reading my messages is way more important than a chat app will not use my phone number for advertisement. Ideally I'd have both, but given a choice, the first one is way way more horrific than the other. Though, for some cases Telegram is definately better, Groups, work related chats don't really need to be private as much and that's where telegram really shines for me. Specially since I can use…

> is way more important than a chat app will not use my phone number for advertisement.

My profile being shown on a different platform to people that I might be close to (co-workers, in-laws, friends of friends) but I'm not interested in having on social media is pretty damn concerning, regardless of ads.
