The reasoning they give is ludicrous. That’s idiotic as saying because someone put up a pedophile website, Apache is the devil. Even if Apache were built by NAMBLA, if it’s opensource and doesn’t randomly insert pictures of naked kids into your website, how does the developer matter to the product?
