Nothing is completely foolproof.

Everybody says this but it doesn't make any sense. Are the repositories going to get more malware when there are more people and funding available to notice and report it?
> Also, there's lot of Android malware that's installed from outside the app store, typically for piracy reasons which is another big malware vector on Windows.
All the more reason why it wouldn't happen on Linux. Nobody really pirates LibreOffice or gcc.
