Sure, I take your point
One could avoid saying “culture” if it seems too thusly broad
But so is calling a film, a song, a book, a tweet, or a TV show “content”
Unless we’re specifically discussing the network in which these pieces of human expression reside — ie the ground and the figure, the database and the data within, in which case “content” *can* be a useful term — “content” is maddeningly vague
