Not necessarily. The sentence immediately before your quote adds some more context: "If we give people control over what they share, they will want to share more." I read that as saying that if people have control over who sees their information, they will become more comfortable with sharing more widely over time. You may not agree with that sentence, but it conflicts with your conclusion.
