I can assure you that Blizzard Entertainment has and will never compromise an account to promote Authenticator use. We dedicate countless resources combating malicious parties, developing security resources to help protect our players, and restoring accounts that have been compromised. It would be wholly counterproductive for us to compromise an account to sell a single Authenticator that is purposefully sold as cheaply as possible (or free on many mobile devices).
Signing up for Real ID will not result in your account being compromised. I'm terribly sorry to hear that your account was compromised, but the act of "signing up" for Real ID does not open you to up to any security threats. It may be easy to blame a new system for your compromise; however, you are only doing yourself a disservice by refusing to accept other more likely security possibility. I strongly encourage you to review the following resources for more information on how to secure your computer and protect yourself from phishing scams:

I appreciate your patience and hope to hear that we are able to recover your accounts in the very near future. Should you have any questions, please do not hesitate to let us know.
Best wishes and good luck.
