Discrimination would be "OMG ICK! NO WAY! NEVER! I DON'T AGREE WITH IT!"
Discrimination isn't "Sorry, but putting that in just isn't cost effective/profitable"
So now you have a problem with anyone saying it's discriminatory and not just certain people?
Discrimination isn't necessarily as explicit as you make it out to be. Really, it comes down to two groups of people being treated differently (intentional or not).
I'm also not sure about the "cost effective" angle, considering there are tons of OGRA content and not all of it feels necessary. Instead of making sure most male PCs had a woman on every planet to "sex up" they could have done a few SGRA romances. But, OMG NO! male PCs need more action! Can you see why that's kind of a problem? That's what doesn't sit right with me. If there were only a few OGRA encounters then it would be a different story.
