I program too. I get your perspective, I think. If we looked at the site's source code, we (probably) wouldn't be able to identify any specific lines of code that were actively anti-LGBT. To see the complainant and the court's perspective, look at the functionality of the site at a higher level. What does it do? It lets people match up for dating purposes. LGBT people - a specific historically-discriminated-against group - could find this as a useful service too. But the site software lacks the necessary functionality to enable this -- and it doesn't need to be this way. So where's the 'active' exclusionary code? There in the program, considered as a functional whole, not located at any more specific location.
