The whole COVID situation forces companies to upgrade plans, migrate from other VPN solutions towards ZScaler. I know about 200 developers using linux in bunch of companies forced to drop linux supported solutions like openconnect towards zscaller. What else should happen, to make ZAPP available for linux users ? A lot of companies have multiple platforms like iOS developers doing iOS apps, linux developers doing Android Apps, or just Java/Node/Docker stuff happening with Linux distros. The VPN market is highly competitive, if ZScaler is not going to compete in the race, eventually someone will win. I am so convinced that if that kind of rpm/deb/sources distribution project appears in OPEN SOURCE, all these people waiting for linux zscaller solution will start contributing because of sitting at home watching netflix.
