I remember some old document or preseident saying saying something about a &quot;government for the people, by the people&quot;.<p>I suspect Google, Microsoft and most businesses involving the Internet and Money at the same time care. They probably want to know about flaws so they don&#x27;t wind up losing their pants like the Bangladesh bank did recently.<p>There is huge money and real lives on the line here, this is not about appeasing message board hackers. Imagine if some big hack was learned to be known about in a 0-day the FBI withheld? I am fairly certain it was Target&#x27;s mismanagement, but imagine if the a document was leaked and it showed the government knew about a 0-day that allowed the Target hack. That is small compared to what might actually happened when talking about browser or OS attack surface.
