I don't feel like you read the article.

They state that this site required a Yale login, and Yale is quoted as saying "all the information on the website remains remains available to students on the Yale site" therefore making the information available to the same audience.

Also the article discusses Bluebook, it having been developed by students, acquired by Yale, and it being the tool which they found less than ideal to use. It even links to the very same article you link to when talking about it.
