As I said, I don't blame the buisnesses for actually selling it. I can't. It's easy money and we apparently are eager to foam at the mouth in order to see pictures moan at us. However, it's the community that decides what content we get, not the companies. Whatever sells, we get more of. And thats Nukige. No, all-ages can't possibly sell more. There aren't enough people who care or pay attention to quality of writing or flow of a visual novel to warrant taking out an H-Scene despite how bad or abtrusive it is. It will almost always sell more if it has H in it. The only thing I can think of is something from Key, who even among the japanese audience has a reputation for being awful at it.    
Again, it's not always bad. Sometimes it's just there and forgettable and is supposed to act like a treat for getting to it. Koihime Musou/Shuffle supposedly sold very well.   
     
 You can't dispute that if the japanese actually saw a market in the western audience they'd be more lenient towards making a deal. Also, C&D notices are mostly by incredibly over-energetic law teams on the company. Very, very rarely do you ever get a C&D by the president himself to ask you to stop making translations. They wouldn't have made it over to the west any other way, so if even a few people are willing to pay the export fee, it's mostly just free publicity. Wasting money on hard-copies and advertising on a market that doesn't seem to have any want nor care for real power-house visual novels would be a terrible buisness decision. There's no market. That is the only reason. Money is what decides it. It doesn't matter if a couple people are xenophobic on the team. Profit is profit.      
     
 Thing is, this isn't limited to us. You're right. Companies can only barely survive making all-ages games. And that's because the thing that I talked about before, community drooling at the mouth for H scenes regardless of quality, exists in japan too. Even despite how good a game might be, people may not buy it simply because of the lack of H. That's why I find H in story-driven games a lot of the time completely cancerous. They offer nothing but fan-service, potentially ruin the flow, and enforce the fact that we need the stupid material in VN's because we are incapable of accepting it as an actual media form.    
I'm not saying I want all story-H abolished. That'd be bad. And an even-now niche community would grow even smaller. No, I just wish it just not put in there for the sake of putting in there. Like relevancy. Written to fit inside the story without seeming awkward. It's not impossible. Hell, a lot of story-driven VN's H-Scenes are tolerable, yes. It just bothers me when things like Little Busters! don't get looked into/bought because "Everything else has H, why doesn't this?"    
Sharin no Kuni, Himawari no Shoujo's H was okay. It was a reward for going through all the crap. Saya no Uta's H was a plot-point. Then there's Da Capo II and Yume Miru Kusuri, who have a little bit of being pointless but tolerable. Then you have MuvLuv Alternatives H which was pointless and terrible. G-Senjou's which was entirely flow killing, F/SN's which was forced & Hoshizoras which a lot of the time was random.    
I might be being too picky about quality. I mean, I did enjoy all of the ones I listed, really. The H didn't ruin the games. Yet, it's annoying to be reminded that companies have to shoehorn this crap in because it won't sell otherwise.
