I, frankly, have no idea

What’s objectionable? Who decides that? Does an abusive parent get to decide that no one should provide any information about abuse to their kid? Do ultra-religious parents get to decide that no one should see information about LGBTQ issues or mental health medication? Do non-religious parents get to decide that no one is allowed to read the Bible online due to violent passages? 

It appears the answer to that, at least until a court steps in to strike down this law, is yes to all of that. As the EFF points out, this isn’t just a risk to the big tech platforms. Anyone with a blog, website, social media account, etc., is subject to a civil lawsuit based on a parent not agreeing with what they post.
