I am the only person in my 10 person team that prefers the cli for stuff like git and while the ratio was a little more balanced during my time at college, it was still skewed towards GUIs. I don't think its unreasonable to think that developers might prefer GUIs over CLI
Many developers are on Windows, and those tend to prefer GUIs. CLI reliance is mostly a macOS/Linux thing.
I know some window developers use use WSL for all of their devving, and they are obviously gonna be working through the terminal.
