Liability: Open Source v. Properietary
"If you’ve heard lately (via Steve Ballmer at Microsoft) that you put your company at greater risk of being sued because you are using open source software (OSS), don’t believe it.
"Actually, there is, depending who you talk to, either an equal or somewhat reduced risk of liability from OSS than proprietary software. This is because OSS code is peer-reviewed by a group of proud developers who often have the ability to recognize other developers’ handiwork."
