The choice between TUI vs GUI is far from that simple. It’s too reductive to say that TUIs are common in FOSS because the state of GUI programming is in such disarray. TUIs are easier to deploy and the GUI landscape is fragmented. But the only reason why TUIs are common is because the users are comfortable with them. I think that the proportion of users who are comfortable at a command line is much higher with Linux, BSD, or even macOS users than other OSs. If the users weren’t comfortable using a CLI or TUI, there would be a bigger push to unify the GUI landscape. Otherwise no programs would get written because they wouldn’t be used.
