Telegram-iOS

GitHub builds directly from their source code just fine: https://github.com/TelegramMessenger/Telegram-iOS/actions/ru... (uses this script: https://github.com/TelegramMessenger/Telegram-iOS/blob/maste...) And here are few recent examples of them helping people to solve build issues: https://github.com/TelegramMessenger/Telegram-iOS/issues/968... https://github.com/TelegramMessenger/Telegram-iOS/issues/986... https://github.com/TelegramMessenger/Telegram-iOS/issues/992... How were you digging to find an irrelevant issue yet omitted all of this? I really don't see the picture you're trying to paint.

Where did you get that idea from? Their client code is not usable because they don't provide working instructions for compiling it. If you can't compile it, they can't have reproducible builds. For example, see this issue from 2019 which the developers still haven't replied to: https://github.com/TelegramMessenger/Telegram-iOS/issues/97 There are a lot more issues about people not being able to use the code, none of which get any replies from the owners.

The Telegram app is native: https://github.com/TelegramMessenger/Telegram-iOS

The source for the clients is available. 1. https://github.com/DrKLO/Telegram 2. https://github.com/TelegramMessenger/Telegram-iOS 3. https://github.com/overtake/TelegramSwift 4. https://github.com/telegramdesktop/tdesktop

you can always build your own app from source IF that's an option. The app itself is open source. https://github.com/TelegramMessenger/Telegram-iOS

All Telegram clients are already fully open. (The server side is not, but there are third party implementations). https://github.com/telegramdesktop/tdesktop https://github.com/DrKLO/Telegram https://github.com/TelegramMessenger/Telegram-iOS Plus a few web frontends, I am way too lazy to find them all. https://github.com/zhukov/webogram WhatsApp forbids third party clients IIRC.

Can you really compile them? If you look at the iOS repo, first there is no license associated with the repo. Second, there are lots of people reporting failed builds in the issue tracker without a response. https://github.com/TelegramMessenger/Telegram-iOS https://github.com/TelegramMessenger/Telegram-iOS/issues/377

you ask them for the LGPL package, they send it to you, you compile ? The onus is on the person making the app that links against the LGPL library to provide you with the build instruction. At worse they would give you their main static library and Qt LGPL source code and you just have to relink them and open Xcode to upload it to your iDevice ? Here is for instance the source code for the telegram app for iOS which is under GPL : https://github.com/TelegramMessenger/Telegram-iOS there is no difference with... basically every other open source project ? Open the .xcodeproj, build, run.

Why don’t “rogue” clients have access to chats? You don’t need to reverse engineer because the protocol is documented and the clients open source: https://github.com/peter-iakovlev/Telegram-iOS If telegram was serious about privacy they’d make end-to-end encrypted chats default instead of a hard to use option and storing your unencrypted chats in their cloud by default.

> I'm not sure about iOS as I don't currently have the means to verify the content of my App Store iOS installed version of telegram I’ll save you the work: Telegram has updated more often that this repository[1] has been committed to, so the code is perpetually out of date, if it ever shipped at all (apparently it doesn’t compile?). The author has mentioned[2] that they will open source their new client once it has been released, but that promise has not been kept. 1: https://github.com/peter-iakovlev/Telegram-iOS 2: https://github.com/peter-iakovlev/TelegramCore/issues/11
