> youngest generation of internet users get this.

They get it because in the jungles of many junior high and high schools, anything that can get you bullied will get you bullied, and young people quickly realized that all the accidental oversharing (by themselves or by their parents, elders, etc.) were easily exploited by bullies.

Thus they came to prefer simpler networks with simpler security/sharing models and features (like automatic photo deletion) that respect user privacy.
