I disagree. We have called online distribution "content distribution" and the people who contribute stories, videos, and art "content creators" for at least a decade. It's a catch-all generic term for all content that another person would consume via a platform. In a general work setting you're probably not producing content for a platform, but you are certainly producing content for your coworkers and customers. It's so you don't have to say: "stories, blogs, vlogs, photos, digital art, products and any other thing that is consumed by others."
Agreed. If anything, word 'content' captured a broader array of work output in the mind of general public than work, which conjures up a lot of things, but rarely artistic endeavors. I do dislike using it as a part of describing my own habits, but it would appear that ship has sailed. In both my tech and non-tech circle, stuff they do is content consumption. I am not sure when it became so prevalent.
