I don't particularly mind closed code, necessarily (and I use OS X in
several places), but that's an excuse that doesn't hold water.

He is assuming it is harder to crack closed source code.  Which has a
grain of truth: it is _very_ slightly harder to find a vulnerability in
closed source programs.

But _very_ slightly.  Most exploits even in Open Source programs are
discovered through analysis of the program produced.  So programs from
closed and open source have basically the same level of vulnerability,
since that is how you find exploits in closed-source code.

So, with the closed source, we have to trust the company when they say the
program doesn't deliberately do anything underhanded, and we can't fix any
problems we find ourselves.  From a security standpoint, that's the
_entire difference._  Any extra vulnerability from being able to see the
code is so minuscule that it has never mattered.

So... Tell me why I should trust Adobe?  ;)
