I really like these sort of games that try to be as minimal as possible, while still being whole games.
Emacs. I’ve created a niceish workflow with it. I really like how it’s so easy to change anything. There are also loads of incredibly useful plugins, so that’s cool.
I find that it’s easier to fix things (though that’s through the terminal, so it’s subjective). I’d say that maybe the best they could get out of linux (appart from the philosophical aspect or the security) would be more alternatives in software (if they care to have them) and better support for older hardware. Maybe even remove some of the problems that windows usually has like the preinstalled apps and slow updates, though that really depends on if the person finds these things annoying or not. (Also, it can be free, so that’s nice)
