Iirc the reason it changed was because it’s a more accurate description of what the material contains, and because actual pornography is supposed to be consentual by nature, even when it’s depicting an imitation of a non-consensual act. However, kids are incapable of consenting. Saying that videos of them is porn feels too much like it puts it on the same level as adult porn, when they’re not at all the same. If someone released a video of someone being raped I think most people would consider it distasteful to call a real rape video “pornography”.

I can understand that reasoning tbh.
