But is there an actual alternative? PeaZip directly uses 7-Zip under the hood. NanaZip is a fork of 7-Zip. While it's certainly a very good effort, it's focused on modernization and AFAIK doesn't fix many of the issues brought up in the article. WinRAR is the "obvious" competitor, but it's completely non-free and also Russian-made (though the company itself is German).
