The article discusses the challenges of creating private client-side-only Progressive Web Apps (PWAs) and how Apple's recent changes to WebKit have made it impossible. Apple's changes erase all local storage data for a given site if the site is not used for seven days, which means that apps must keep data on a server or risk losing it. The author argues that this change hurts the web and forces developers closer to Apple's app store. The author was trying to build a feed reader PWA without a backend server, but Apple's changes have made this impossible.
