I do not think the author doesn't know that section 1201 was designed to help companies create access control. The author of the blog post is talking about not just the purpose of the law, but also the effect, which he or she believes infringes on the First Amendment. I'm not a lawyer, but I think that laws with a constitutionally valid purpose are sometimes ruled unconstitutional by the courts when they have unconstitutional effects. I can't comment on whether I think that will be the case here.
