Extroverts can be bad team members when they're assholes. Assholes come in many flavors, but an extroverted asshole often makes a worse team member than an introverted asshole.

I think the article is talking about a specific way of talking about "team skills" and "communication skills". Some people tend to equate those terms with the ability to make small talk with everybody, be popular at parties, etc. Those kinds of "skills" are definitely lacking in introverts, yet expected of everybody where extroverted assholes are in positions of power.
