Boycott 7-zip: "Limited" Open Source & Security Issues
"Limited" Open Source 7-zip developed by Igor Pavlov, first release happened in far 1999. Licensed under LGPL-2.1-or-later, but one detail: you can't find the actual sources on Github, Gitlab, nor any public code hosting, only src.7z on official Sourceforge page. No history, no committers,
