It's also important to note that if we mandate that every piece of content must be maximally fair to everyone involved, it means adding less choices too.
For example, if we look to add some content, but feel that only a subset of people will be able to enjoy it, if we mandate that we need to fully equal for every aspect of the game, the only option is to either ensure it's fair and equal, or to cut it.
If the ability to make it fair and equal (which might be subjective, depending on the context) isn't there, the only option is to not add the content.
You could also say, that by trying to maximize the content of the game and thereby adding more and more choices, you risk that only subsets or only one subset will be able to enjoy the content. Mass Effect 2 and The Old Republic might be two good examples.
I realize, this is not the case with Dragon Age: Inquisition, but several players will inevitabely feel dissapointed because certain companions will only be romanceable for a certain gender and/or race. I also realize that Bioware can't satisfy every player, but it is my believe that by sharing content fairly and equaly you would satisfy the most of them.
However, I don't think, that there is a perfect solution for this. So in the end, I am just grateful that you decided to offer multiple companions for the LGBT player, especially because not many developers bother to do so.
