Hi, PeaZip author here.
While I appreciate (and thank) the effort of FlatHub community in building and maintaining a Flatpak version of PeaZip, I would recommend to most users to chose one of the available Portable packages for Linux https://peazip.github.io/peazip-linux.html to test the application without requiring installation, with a 12 MB download.
About the main topic, I'm saddened the moment we are living is threatening our long-living assumption of the possibility of a world where people of different countries and cultures can freely cooperate for a common good, which is one of the main pillars of Open Source spirit. I can only wish Igor to keep up the good work.
