Re: Should be part of their threat model
"Not warning users is a serious oversight."
Truly, but it is also vital for any user to check files they download, and I would say especially anything to do with Wikileaks, given their attitude to not redacting location information for Afghan informants and Assange's reasoning for this. I check anything I download with 3 packages I've installed. There are also the on line checkers for more paranoid people.
