Neither. As the article specifically mentions, they will not be charging for the existing open content, or any future changes or additions to it. Why you would try to suggest they might do this is beyond me. They will be selling additional "premium features" at launch time, as described in this article, and plan to sell specifically created additional content, like in-depth articles, in the longer run, as described in previous articles. Maybe this will enable them to hire back some of the people they let go (assuming these people are willing). But the main goal is to put mdn on a level of funding where little or no funding from mozilla is required anymore.
