I know. The author suggests:

Experiment with new-to-you version control systems like Fossil, Mercurial, and Pijul.

The author is:

learning about different version control systems. For example, the differences between Fossil and git revealed a lot of my biases towards git simply because it’s familiar (and Fossil seems really cool). Reading about the theory behind Pijul absolutely bends my brain into knots. I keep trying anyway because conflicts in git are frustrating and I’d like a better solution.

The author says:

It would be nice to move beyond git one day and have a better experience for managing complex codebases, and not on GitHub’s timeline.

I think it’s valid unless one thinks git should be the only standard. Looking at other tool chains opens options

Did you read the post? The author suggests trying out other version control systems too.
