Fair point but the different or key factor now as with alot of the areas AI touches, the problem isn't the tools or use of them exactly, it's the
scale.
In this case the low barrier to creating the media/posts/whatever coupled with the pervasiveness of social media networks and their reach (also networks that aren't new), affording the rapid deployment and significant impact by bad actors.
The problem is the scale. The scale of impact is immense and we're not ready to handle it.
