That's a logically false inversion, assuming you take 'no better than' to mean '<=' (as I think makes sense in context). OSS <= CSS does not imply CSS <= OSS..

OSS <= CSS does not imply CSS <= OSS... > why on earth would you ever choose closed source components There are often no open source alternatives to closed source things that are meaningfully equivalent. For example, the iPhone is a secure and closed source phone. There is no open source equivalent to that package. Android devices have critical closed source components with almost no exception, but also are not equivalent to an iphone in many meaningful ways. I think a better take-away is the nuanced "evaluate things on a case-by-case basis, don't let a security system having closed source components needlessly bias you"
