If we are so concerned about the materials make the platforms moderate them like they used to do. Banning them reeks of favoring the murdoch outlets which are free to spread misinformation
Murdoch benefits from the political agitation that the landscape of social media provides.
I do agree on making platforms moderate themselves. This legsliation helps do this by creating a discussion about the harms, enforcing a culture of harm (this is not for all ages, not default for everyone). Saying to the companies: "Hey, if you don't want to be regulated, clean up your platform so it's safer". Will that happen? no idea, but if it doesn't, no children is still a good goal (it's how you get there that has the contention).
