“Open-source guru Eric Raymond explains why you should use
software developed by a community of peers.”
“The first law of closed-source security is that only the bad
guys ever get to see bugs. Talk to any cryptographer. The
cryptography community concluded years ago that closed algorithms
simply cannot be considered secure because they have not been peer
reviewed, because potential bugs have not been exposed to scrutiny.
There’s nothing special about cryptography that makes that a unique
insight. For the same reasons, you just can’t trust closed source
anywhere that security and reliability is an issue. It comes down
to a very simple question: How can you audit a program that you
can’t analyze?”
