And as others have pointed out, closeness isn't always an advantage. Dave criticized the EFF post by saying
"This is a fundamental misstatement of how 0days work in the real world—in reality, the vulnerabilities used by the US government are almost never discovered or used by anyone else—and these falsehoods further confuse the conversation about 0day policy solutions."
Except of course that as the Shadow Brokers leak showed, quite a few of these vulnerabilities _have_ been discovered (and for all we know, used). The risk of something like this happens is something that EFF et al. always bring up, and the intelligence agencies and their supporters always dismiss it ... where's the "falsehood"?
