so, there's no way for true privacy/safety online, even off line.
IDK what you mean by "Safety", but nothing about these leaks indicates that there is no way to maintain privacy on or offline.
The security community has been aware that various fedral agencies, mostly the CIA, NSA, and FBI, have been finding and stockpiling 0-day exploits for various pieces of software for decades.
There are active exploits for a lot of systems, but not all, and most aren't passive exploits, they require a directed hack into your computer before they can be triggered.
How do we approach this situation ? As a nobody, i am not really affected, as long as i remain a nobody. But, keep in mind that any idiotic, compromising or sensitive shit you ever put on any electronic media can be stored and used against you years from now, and that is scary.
Well, don't say idiotic, compromising or sensitive shit online, that was easy. If you need to communicate securely, there are a number of options that aren''t compromised.
