No, it's not. The author used the blog post as supplementary material, but like Steve Jobs the author also had the common sense to take away his child's access to electronic devices for reasons outside of the content. More generally, when somebody is too young to consent to something - the decision their rests with the parent. As the author alludes to, this is mostly done just to silence the kids up rather than enrich their development. I think the content here is far less concerning than this increasingly common 'tablet-babysitter' behavior.
