It isn't the education system's job to produce model employees. Nearly all the "modern skills" mentioned in the article all squarely fall under the moniker "industry knowledge", which is... the industry's job. Those that don't fall under the umbrella of maturity, which only experience can teach.
In my opinion, employers should start investing in their employees again, as they once did. It's neither morally laudable nor enlightened self interest to throw someone in the deep end and expect them to swim. And in our capitalist system, it's self-indulgent to say that you want something without paying for it. That is ultimately what the article is proposing: that open source contributors sacrifice their spare time to be the mentors companies should provide.
