I decided to create a new account with another email address. I still have access to the books that were on my desktop on my desktop, but not on my phone and I lost a few library books, but they can be borrowed again for free. It was a much saner solution than trying to talk to Adobe Tech.
iTunes does allow deauthorizing devices from a desktop logged into my account. I had to do it when my pc crashed and I needed to deauthorize it and then authorize a new computer. I had to call for help. It wasn't easy but the support was there.
