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.
Not only sold, I used to report bugs to Wire by e-mail and GitHub before of the change.
One day, they just sent me an automated message in which they said they would not going to provide support to the personal edition at all during a time because of the lack of staff while providing support to the business edition.
It passed more than a year and was maintained, I don’t know today but I expect the same.
Edited: I don’t know why I put Signal instead of Wire jajajajajajajaja.
