Telegram

Telegram is a great messaging app filled with features. In particular it has broadcast channels which can be fantastic for sharing information widely. But is it suitable for group chats?

Security

Although Telegram's website would have you believe otherwise, Telegram actually provides the worst security out of all the apps being compared here (source, source).

One of the reasons why this is the case is because Telegram group chats are not end-to-end encrypted. Telegram does allow users to have secret chats with self-destructing messages. However, this is not available for group chats so all of the messages that you send to a group chat will be stored on a server somewhere accessible to the authorities.

Another serious problem with Telegram's security is that messages are sent using Telegram's own private encryption protocol, as opposed to something used more widely. This means that it has not been as thoroughly tested and many security vulnerabilities have been exposed in the past.

Can be compromised if malware is installed on the phone or computer, or other people have access to that device if they use your login. Or if you have infiltrators - no app protects against those.

Accessibility

Telegram is one of the most accessible apps available. You don't need a smartphone to sign up, just a phone number, and it can be used on practically any device.

Features

Telegram is very useful for broadcast channels (in which only admins can post). Links for these can then be shared on wider channels (eg. Rebellion Broadcast). However, widely shared links attract spammers so they need to be carefully moderated.

Discoverability

Telegram has some excellent features that make group chats easy to find and join. Like Signal and WhatsApp, users can share a link to the chat that people can use to join it. However, you can also search for public Telegram channels from inside Telegram. This makes it easy to find and contact broadcast groups but can also lead to spam since anyone can join these channels - even if they are not a member of XR.

Drawbacks

Telegram is really a social media platform and has a very ‘relaxed’ content moderation strategy- this means it is targeted by spammers if you have open channels. You have to be on top of moderating it!

Some people find it difficult as you can't save messages for later or mark them as unread so you constantly lose key info and can't find it again.

It's limited in terms of formatting messages and if you want to broadcast and add an image there's a character limit so you have to be able to either fit your message into that limit or miss out key info.
