I've commented in the past that the privacy community is diverse. I divide the community into (at least) two major groups:
- People who believe that privacy means being able to anonymously use services.
- People who believe that privacy means being able to control what other people do with data about you.
These are not compatible views, and they often conflict with each other -- both philosophically and practically.
If you believe you should be able to compel a business to delete data you gave them, then necessarily there needs to be a way for that business to confirm your identity and link you to that data. You become more concerned with this idea of "owning" information about yourself.
If you believe you should be able to do everything anonymously, then it becomes much harder to control information after it's been leaked. You can't implement things like geo-locking users because what you do with the information doesn't matter -- just collecting it is a problem.
If you're in the "everything should be anonymous" crowd, you're also less likely to agree with efforts like Right to Be Forgotten; you may even reject the idea of data ownership entirely. For someone in the "I control my own data" crowd, the Right to Be Forgotten is absolutely critical -- it's one of the most important safeguards we have against a future where everything is permanently indexed forever.
I'm oversimplifying, but at the moment, the majority of pure-tech solutions for privacy are on the "everything should be anonymous" side, and (at least for the moment) most legislative solutions are falling into the "you should control your own data" side. That leads to conflict. Not always, but sometimes.
It's important to keep in mind that even though the privacy movement is aligned on many issues, there is no binary "pro" or "anti" privacy, because there's disagreement from privacy advocates on both where we're going and how to get there. In this case, California's law is very much a "control my data" law. Points like, "Businesses would be required to comply with official consumer requests to delete that data" conflict with the way that "be anonymous" privacy advocates see the world.
