TL;DR: The standard now provides an "official" definition of what makes a project open source hardware (i.e. what has to be under a free license to ensure the project is actually usable for others). This is useful e.g. so research projects looking for public funding can promise to deliver open hardware "according to DIN SPEC 3105-1". The article also addresses the conflict between "DIN" and "open", because DIN is mostly known for locking away critical standards (that are often incorporated into laws by reference) behind expensive paywalls. This standard is an exception and according to the article, the first standard that's open source itself.
