Yep, I didn't see why the author decided to snipe at Emacs and Vim at the end of the piece. Maybe 4 or 5 years ago, that criticism of Emacs would have been valid, but packages like flycheck and lsp-mode have brought Emacs at least to parity with many IDEs. In terms of Git alone, Magit has catapulted Emacs past any other editor, IDE, or Git GUI client.
