Then let's try some mostly informed speculation.

Well, there have always been a number of factors reducing sales on certain doujinshi titles. It may be the author, the publisher, or fans squashing doujin piracy. Titles that have their manga versions marketed or distributed by Shogakukan and Shueisha typically do not have doujinshi versions sold by a number of online japanese retailers or even by amazon.jp. Shogakukan has an anti-doujinshi copyright notice on their company webpage with the threat of lawsuit. So it is not a subdued polite "please don't do it". Shogakukan is one of the two primary parent owners of VIZ (their american english localizer) and all the active fans would know of at least some of their effects upon english scanlation for 2012. Not that the piracy has stopped, since the piracy for profit websites of mangafox and other aggregators continue to put up the manga warez since they are mainland china based.

The lack of doujinshi for specific titles can also be due to the author/artist/media rights manager (typically the publisher) have a special hard-on for that product. For example, Fairy Tail doesn't get many doujinshi made due to difficulty in selling them on a long term basis, and because there are avid fans that immediately report fairy tail items for deletion.

If a doujinshi cannot sell because retailers know the publisher doesn't want doujinshi to be sold for certain items, then as a doujin author, you know that the total number of sales will be less. Would you rather spend the same amount of effort on something that would sell way more instead? After all, there is no use in making it unless you plan to spend a lot of effort finding the venues to sell it at. That can be done if you are a big enough maker to regularly attend and commission or put up your own table at least at one to three major doujinshi venues per month. It would be game then how long you could sell before the company caught up to you. But quantity sales is difficult if you cannot use standard retailers (online, mail order, and storefronts).

Now, the smartypants here would say, "why doesn't the doujin author just make more doujins then, and the ones that sell great do to no interference from the copyright holder will sell well, and the others will probably sell enough to break even before they can't be sold anymore". The problem is that an author doesn't always get as many "shelfspace slots" as he wants. He might get only one slot for 2 weeks. If it sells well, it may be extended, and he would have a higher chance of returning in the future when more sales slots are available. If the item sells poorly, then that might negatively influence the author's reputation at that retail chain. So, one cannot just throw out merchandise for sale.
