Technically, my distrust in Steam stems from the fact that they implemented a region lock on all AO games in my country (completely out of the blue), which is not only not required by my country's laws but might even indirectly violate free market laws in my region. So when you say Steam has become a more adult-friendly place, you're probably right, but you should also be aware that Steam can and will pull that rug from under you if they ever feel it's the easiest option for them to avoid controversy.
You do have a point about AO games rarely being fully removed from Steam anymore, though. I guess unless Ravager gets some kind of content added during the EA period which directly violates Steam's rules, it's probably not at risk of being removed. Let's hope for the best so at least other people get to enjoy the full game :)
