Important notice from #Signal: Info circulating that signal would be hacked are just rumors to stop people from using secure communication options. Encryption saves lives.

#Signal is way more secure than #Telegram.
But while Signal was not hacked AFAIK, there are a few issues:
1. The client is no longer fully open source: https://signal.org/blog/keeping-spam-off-signal/
2. The server was closed source for a long period which shoud raise eyebrows.
3. Their servers are hosted with PRISM-connected companies, allowing observers to analyze the traffic.
#Briar should be a better option IMHO.
