Most of the security benefits come from giving the vendor an incentive to update their software quickly. I've often seen proprietary companies delay security critical patches until the next release or sue well meaning people who are reporting vulnerabilities (to the companies) as hackers to hide evidence of vulnerabilities.
There is a reason why so many vulnerabilities are found and reported in Linux compared to e.g. Windows. There is no censorship that tries to make the world look prettier than it is.
