The short answer is no, the judge was wrong. For the long answer, you'll need to revisit a case in which the Texas Bar Association tried and failed to suppress self-help legal books and software. You'll find the whole story right here on Nolo's website.

Fortunately, other states have not attempted to take the Texas anti-consumer route. Courts have consistently ruled that creation and use of self-help legal books, software, and forms are in line with every American's right to self-represent.
