I think the proposal is fundamentally flawed because of this reason. Facebook, Instagram and X/Twitter are probably what's intended here, but what about Tumblr, DeviantArt or Discord? What about Reddit or a generic forum? What about VRChat or Webfishing? If this is about protecting children from harmful depictions of body image or misogynistic content, then why not instead propose a law that states online services that allow children to join need to appropriately moderate the content that is shown to children or could face massive fines. I don't necessarily agree with that approach, but at least it would make sense with what their stated objectives are.
