LOL.
That's like saying, if I like watching lesbian content, I must be a lesbian, just because you like watching some content doesn't mean your sexuality automatically changes, it's called fantasy/kinks, it's pretty rude of you to just call people gay because of the content they like to watch.
The dev hasn't focused everything on Riley, there has been content with the whole cast (mommy/daughter/pam) last update had most content.
I think you just see it as more focused on him because it's the content you may not like, which is fine, you either like it or you don't.
You have the option to skip the Riley scenes, but just keep in mind, not every update will have all the content you specifically like, it's just the way it is.
