I'm young enough that Git became the standard before I was even into programming, so I didn't witness this happen in real time.
On Windows, Git requires MSYS2, Bash, and some other tools from Linux to run, although the installer is nice enough that it's not too much of a hassle. However, from what I've read secondhand, it wasn't always nice.
According to Statista, 61% of software developers used Windows in 2022, and it was similar in precision years; however, it seems like some amount were dual-booting (Windows + MacOS + Linux/other Unix adds up to more than 100%) [1].
Given that, why didn't Windows users establish something like Mercurial as the standard, given their majority/plurality status? Or did something like that happen?
