I know, right? Developing anything on Android, for example, requires Java or Kotlin, tens of GB of SDK stuff and emulator images (if you don't have a device with the specific Android API you want to target), and using Android Studio or fighting with gradle manually. Or you could 'root' your device and fight with Android to run your arbitrary scripts in a severely reduced shell.

I'm sure some Android dev is going to say "but what about blah blah new API new tools whatever?" in response to this.. but my workflow is autotools or meson (and for the Librem5 a crosscompiler) + vim. Or I could write shell scripts using a plethora of cmdline tools and not install anything extra to develop useful, powerful stuff for this device.
