Yeah, I think you raise a good point here! "Culture" has meanings far beyond "a single piece of human expression", which means it can't swap in place for "content" every time. And as some design friends pointed out to me last night on Mastodon, in design/UX circles and the like, "content" is sometimes/often the most useful word they have -- perhaps, they say, the only word they have -- for distinguishing, say, the form of a project (a web site) from the information it conveys.

I've actually taken that point in and added a caveat at the end of the piece -- noting that my issue is less about how "content" is used industrially in design/UX circles, and more about how it has crept out into mass usage, and particularly in the C-suite.

That said, I don't have a better solution than the "culture" one I recommended, so you got me there ...
