Yeah, that cache of zero days and all those DLLs aren't for mass surveillance. Ok. That's super duper believable.
By design, a zero day cannot be reasonably used for mass surveillance. Every endpoint targeted increases the chance of discovery. This is how many would probably prefer to see a spy agency be operating; Focus on their specific targets instead of dragnet surveillance.
As for this specific release, it requires physical access (and a very outdated OS).
If the CIA is able to use those zero days on systems which provide them access to larger sets of information, then what you're saying is objectively wrong.
