KodExplorer

KodExplorer (and its next-generation successor, Kodbox) definitely cannot be considered open-source. Although it is published under GPLv3, its alleged source code repository (https://github.com/kalcaddle/KodExplorer) contains obfuscated PHP code (https://github.com/kalcaddle/KodExplorer/blob/master/app/controller/utils.php). The frontend part is only available in minimized form (https://github.com/kalcaddle/KodExplorer/blob/master/static/js/app/src/app/main.js), not the source form before building. This directly violates GPLv3's definition of source code, which is "the preferred form of making modifications". Things only get worse with the next-generation project, Kodbox. The obfuscated code is no longer named "util.php" but "data.bin" under the archiveLib SDK (https://github.com/kalcaddle/kodbox/blob/main/app/sdks/archiveLib/bin/data.bin) and has been run through multiple layers of obfuscation. The frontend code is also heavily obfuscated in a way that it ceases to work even after smallest modifications, and it even tries to load a "updater" script directly from their servers, which can be considered a backdoor. All of these are a direct violation of user rights under GPLv3, and legally sound copyright violations if it uses another library licensed GPLv3.
