You don't know much about business, do you? ;-) Most businesses do not trust anything "open-sorce" by default. Most businesses prefer other businesses supplying their solutions, including security. Most businesses' security implementation is closed source. (And when I say "most", I mean, "from all the companies I have worked for in the past 25 years, 100%". Feel free to do the substitution in all cases the word "most" was used in the above paragraph.)
