Reverting to Form
That is an interesting article and raises a lot of nice points :)
For me, I see the technology as a massively positive influence in all things sexual. Without going into too much detail; without it I would not be the confident, happy and successful person I am today. Finding that I was not alone in the kind of things I like really brought me out of my shell.
What I see more and more really is humans reverting to form. You say that it takes a long time for society to adapt to change and you are right. The thing is, the very prudish society of recent times was actually very short lived. Look at how people acted in pre-Christian times - much more liberated.
Humans, both male and female are very sexual creatures and always have been. Combine that with our amazing ability for abstract thought and it's no wonder we have the wide and wonderful variety of sexual desires that we do.
The Internet and technology in general is helping people to embrace their desires again and opening up whole new possibilities and after we've been repressed for so long, it's wonderful. And the best part is, no matter how much "they" try to stop it happening, it's going on anyway - it might not happen in our lifetime but future generations should be MUCH more liberated, happy and accepting of others than ours. And Good on them :)
