Online people are not "open about some parts of their life voluntarily in ways that the offline-borns wouldn’t". Given how Facebook and such services work, they're being open about everything they do online with service providers which (they hope) will only divulge what they choose to the people that they choose. The online generation, technically speaking, is giving away their private information to third parties which (in their TOS) state that they take no responsibility for it, make no guarantees about privacy, and will comply with government requests if they believe it is in their best interests. The problem isn't that governments can require service providers to hand over the data, as many of those service providers are usually very happy to comply. The problem is that we are using services implemented in a way which does not conform to our expectations. Chatting online with end-to-end encryption and trustworthy software and hardware is reasonably analogous to chatting in real life: you are communicating with the individual identified by the key, whom you trust not to share your conversation with the world. Chatting on Facebook has nothing to do with this: you're chatting with a third party that you assume is relaying the messages to someone you assume is the person you want to talk to.
