How do you define cybersecurity? To me, it is the resistance of computer systems to unauthorised access of any form. And how do you define digital privacy? Well, to me, it is the ability to keep secret anything I wish to remain secret. Okay, so how do you keep secrets on computers? Well, by preventing unauthorised access, of course.
This is why I say that security and privacy are the same thing, and if you try to give up some digital privacy to get better security, you're going about it completely backwards. What people are usually thinking of is spycraft and, in that case, yes, giving up some of your digital privacy does result in easier spy work. Just keep in mind that spies aren't (directly) keeping you safe. Spies are, in essence, a kind of covert *assault* force. The extent to which they keep you safe is just the extent to which they manage to smite your enemies. If everyone has different locks on their doors, then breaking into one house doesn't open up everyone to attack. The thing is, online, everyone lives behind the same door.

PPS - Like all analogies, that one has its flaws.
