GoldBug Messenger is still out there doing really
scammy things too, never audited, never reproducibly
compiled, authors caught lying, censoring users, responding to questions, trolling sensitive lists
to install and use it, etc.

It is so important to support open source software. So individuals can modify them to their needs, build them to their specifications, and review them freely for anything dangerous.
