False analogy given by this federal judge. App stores are gateways to social environments and unknown or future content. Every book in a bookstore can be verified because the content can be known and audited. Regardless of opinion on the root issue, this judges statement aligns books with the Internet and they are absolutely not the same.
> Every book in a bookstore can be verified because the content can be known and audited
A bookstore with a single employee can no more verify the content of every new book or periodical put up for sale than Apple can verify all new content on the internet.
Books and periodicals come out far, far too quickly for an independently owned bookstore to read first. Never mind new books which have set release dates where bookstores might not get advanced copies for books sold on consignment.
With that argument you could argue for age gating wifi access and mobile data.
Yes, but you can't stop eight year olds from grabbing a James Patterson or Stephen King novel from the shelf. Their parents should, and some librarians might throw a moral exception to their choice, but if they wanna read It, they're gonna read It.
Enforcing anything other than that is a huge 1A violation IMO.
