This article mixes up a bunch of different things.
Being a good communicator doesn't mean you have to be an "extrovert at work". There are many different styles of communication. I tend to be the guy who prefers async communication, will write explanatory comments on my own PRs, documents the WIP state on my tickets (especially before weekends or vacations etc.). Others are the kinds of people that'll happily go over a PR in a call. You just have to find modes of working that sort of work for everyone.
