As long as there are no laws there will be companies who will provide these services. There may some companies that still have some ethics and won't serve that market . But the result will that companies with even less ethics will move into that space. I suspect the companies you are mentioning didn't pull out for ethical reasons but because they have other products and don't need that market.
