Stuff like this and MobileCoin is throwing me off a bit about Signal, I know the court orders show they don’t collect much data (just Unix timestamps I believe), and that encryption happens locally, but some parts of the server being closed-source and some questionable aforementioned decisions don’t sit right with me.
I have no reasonable suspicion though, and all evidence points to Signal still being a very secure and private service, so it has remained my personal choice for private messaging. It’s easy to use, looks beautiful, and its easy to get people on it because its pretty popular (perhaps mainstream) at this point.
