It is already called ECMAScript; they do not need to change it. It is also called JavaScript. (I don't know if there is trademark issues with ECMA too though)
However, the name "JavaScript" (and "ECMAScript") is in use enough anyways (like is described in the article), so Oracle shouldn't properly restrict others to use it in this way.
