Or, git is both very complex and very useful, and a large portion of its users have a poor understanding of git but enough for it to be a useful tool. If you want to do source control (which you do), then you’re investing time into learning git and/or fixing git, or maybe using a project like this.

You literally just said what GP said in different words, but prefaced it with "Or" as if it's a disagreement. What you said boils down to "inadequate training".

We both agree that they didn’t know the tool, but GP seems to blame them for deciding to use the tool without training. I was more or less defending their choice to use git, while also acknowledging the potential of a tool like Diversion. My interpretation of GP was that it doubled down on git, while claiming that anyone using git without understanding it is “doing it wrong”, which I agree with in principle but not in practice, as I argued in my initial comment.
