Thinking about this recently and I’m wondering if part of this is that OS developers have stopped providing common services as part of the OS and part of it is that many apps aren’t coded to the native services the OS provides in the first place. Most apps that throw a startup process in the background are probably aiming for (in part) an auto update service. Why don’t OSes provide a service that an app can register a URL to check for updates at? Yes the App Store does this for apps installed there, but outside the App Store there’s no way to do that and to my knowledge nothing like that exists for Linux or windows (barring the few things that seem to be available in windows updates). The other part of course would be even if the OSes did provide this, who would write code for it? Maybe electron would have a function to register with the os native endpoint but until/unless they did, would any electron devs code for it or would they keep writing their own services?
