When people claim that leaks "get people killed," they're referring to when undercover agents are identified while they're in the field. The only secrets exposed in these leaks are the computer hacking techniques used by the US to spy remotely through compromised devices.

The so-called Vault 7 leak revealed how the CIA hacked Apple and Android smartphones in overseas spying operations, and efforts to turn internet-connected televisions into listening devices.

You could maybe say that closing off those surveillance channels prevented the CIA from learning about some attack, but that's really tenuous. It also assumes that the CIA isn't constantly developing new zero-day exploits so that they can continue to spy on just about everyone on the planet.
