You're confusing 2 things.

Facebook shared data on millions of users to Cambridge Analytica. I never gave my consent, you never did.

It is a different matter than having open APIs that allow you to get your own data out of Facebook.

I want to be able to get my own data on Facebook through open APIs. What I don't want is for Facebook to give away my data to other people without my consent. You can advocate for those 2 things at the same time.

Both cases are the same.

Alice sends Bob an email and Bob then shares it with an evil 3rd party spell check extension... Alice's privacy has now been breached without her consent.

Alice posts her contact info to her wall, and her friend Bob (who has read access) shares it with a third party (Cambridge Analytica). Alice's privacy has now been breached without her consent.

Cambridge analytica collected the bulk of their private data with the consent of a friend of the victim.
