I don't think I'm the only one though, at least to a degree. When the only thing you allow your users is to read the source code, you are technically open-source, but it's the kind of openness that doesn't guarantee anything. More and more often companies use the term "Open source software" because they know that people will walk around the internet and say "it's safe and secure: after all, it's open source!"

OWS is aware of this, which is especially valuable when you brag about privacy as a communications network, but they deliberately chose to limit what you can do with said "open source" – to a degree that's quite ridiculous for a company that calls themselves "Open (...) Systems" :)

You're mixing up rights to the software with rights to Signal's name and infrastructure.
