The moat is that Coursera can bundle all of these into a single package and sell it in bulk to these companies. No one wants to deal with this themselves. At the FAANGs that I have worked at there were teams devoted to this task, but it is the sort of thing which is easy to outsource and when it comes to certain compliance courses you sometimes need a legal imprimatur for the course that is a pain for each company to certify but easy for someone like Coursera to do. (I am not downvoting you, just commenting on why some people might be doing so...)
