The Signal Server repository hasn’t been updated since April 2020. There are a bunch of links about this here but I found this thread the most interesting.
To me, this is unforgivable behaviour. Signal always positioned themselves as “open source”, and the Server itself is under the best license for server software (AGPLv3 – which raises questions about the legality of this situation).
Signal’s whole approach to open source has constantly been underwhelming to say the least. Their budget-Apple attitude (secrecy, i.e. “we can never engage the community directly”, “we will never merge/accept PRs”, etc) has lead to its logical conclusion here, I guess. I have been somewhat of a “Signal apologist” thus far (I almost always defend them & I think a lot of criticism they get it very unfair) but yeah I’m over Signal now.
Don’t trust computers, sure. But specifically apps from the US? come on… Most governments have got people on the payroll to defeat cryptography, not just the US. China, Russia, France are not doing ANY better than the USA in this regard.
All governments are psychopaths by nature, and the only way to protect ourselves is to never ever trust a government. (Better yet, burn down all governments and start to live free)
