Simple logic shows that the warning in revelations is not for the whole bible. The book of revelation was written before the bible was put together and even before many other books were written. If the warning in revelations applies to the whole bible, then it must have been added in when they put the bible together ( a violation of the very warning), or it was added in the book of Revelations, with prior-knowledge that there would be a complete bible to which it would apply - an unlikely scenario.
The bible is not a book, bible means books. A collection of books. The warning in revelations is most certainly only applied to the book of revelation. The words of the prophecy of "this book" i.e. Revelation. It is the book of Revelation which Jesus told John to write and distribute to the churches:
Rev 1:11 saying, I am the Alpha and Omega, the First and the Last. Also, What you see, write in a book and send it to the seven churches which are in Asia: to Ephesus, and to Smyrna, and to Pergamos, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea.
Jesus did not give such commands to the apostle Paul for example with his letters to the Ephesians etc. That's why there is no such warning at the end of Paul's letter to the Ephesians.
The warning in Revelations is a form of ancient copyright protection. So unless a person is deliberately changing the meaning and selling them as "books of Revelation" in order to spread false doctrine, it's not breach of copyright. A "fair use" principle would apply, and that includes paraphrasing.
