Source code isn't necessary. How do you think the security researchers find them vulnerabilities? They can fix them the same way too.

You can find vulnerabilities using a variety of techniques, but to properly patch them you do need access to the source code. These "updates" don't even modify the executables, so would have to be applied every time you turned on your P.C.
