The headline's somewhat misleading. What the court seems to have ruled is that the functionality of a program or programming language can't be copyrighted. The language itself (implementation, specifically) is still copyrightable, but the concepts it implements aren't.
Bot also added that a programming language cannot be protected by copyright since that is an element allowing instructions to be given to the computer.
So it sounds like programming languages are considered inherently functional, and thus not covered by copyright.
somewhat misleading is fair. But after I got past my initial confusion I found that I like the headline, as it reminds me of what a programming language is. Node.js, for instance, isn't a programming language but people often call it one.
