It definitely opens opportunities to more people. I personally like that it provided more opportunities for more “natural” women. A lot of porn in the past had overly made up women with breast implants and other plastic surgery. I love that we can see a 50 year old mom or a 19 year old college student explore this space and we can appreciate their bodies and sexuality for what they are.Like much of the online world, the fact that anybody can create and post content now has led to an explosion of variety. We are no longer constrained to what certain magazines choose to show us. This circumstance seems to show some interesting aspects of male (or female) preferences. Many women would be hard pressed to compete with "conventional" models and porn stars based solely on looks, but those traditional mediums also present content that was rote, unimaginative and obviously fake.
Obviously some OF content suffers from the same dynamics, but it leaves room for creativity and ownership of one's content. That allows more niche content and the ability to explore different themes rather than just pumping out images/videos to feed a distribution channel. And it seems to engage a lot of women who wouldn't indulge this sort of thing at all if they had to do it under the control of someone else.
In a way it is a bit like the impact of streaming services. For decades we were fed whatever programming network television wanted to feed us. Most of it was and is absolute garbage. Part of that is the business model and their focus on getting to the widest generic audience to optimize ad revenues and not offend anybody. But part of it is a by-product of the networks' own myopathy and the fact that many creative people do not want to work in that environment.
When we think of any look or theme in erotica or porn, if it is left to the traditional porn industry all we will ever see is drool inducing fluff for the knuckle dragging crowd. Nothing wrong with that. I jerk off to that stuff too. But there is no need to be limited to that.
