Many large software companies develop some of their software in the open, recognizing the benefits of such transparency. You only have to peruse Github and other repo sites. The idea of developing software in the open is widely adopted, and practically a requirement for some kinds of software, like cryptography and other security software.
It seems more natural to draw the exact opposite analogy: If proper handling of livestock and meat is critical to one's safety, meat production should be as easy to monitor as "git log" for a repo of crypto software.
