Manga and novel industry tightening censorship?

Bokurano author Kitou Mohiro has announced on his site that the Bokurano special chapter that would have been on the next issue of IKKI has been canceled and will not be published at all. It sounds like he had already completed work on it too.
He says there is the possibility that he might still be able to get it out in some form in the future, but nothing is decided yet.
Square Enix’s GanGan Online has announced that the release of upcoming light novel “Kurai heya” by Karabe Yousuke has been canceled due to various unspecified reasons. It’s a complete new story so there is no information on the contents, but the title sounds like it might have been a horror story.
The author Karabe Yousuke says on his blog that he was told that the reason for the cancellation was because the story that he wrote was against the ethics regulations of the company. He made a proposal on how he could change the story, but it was apparently not a problem with how the ideas were expressed, and it was impossible for him to change the story in any way that could change their decision.
He had already submitted the manuscripts in April this year and was given the okay by the editor in charge but was suddenly informed of the decision to cancel the publication of the novel early this month.
Karabe Yousuke had previously written novels such as PSYCHE and has long been suspected to be eroge writer Setoguchi Renya who wrote the scenario for games such as Kira☆Kira and CARNIVAL before retiring from the eroge industry.
