@timefiddler A lot of it depends on who you are as a publisher, from what I can see. And how you publish things makes a difference, too.
If you go back in time, there has been a loooooonnnnggg discussion about who has which books. For several months, it was "difficult" to get some of the Demon Lord books in Germany because the covers were considered objectionable; Amazon.com had them, but Amazon.de did not. That applied to both print and electronic versions.
I sort of left that discussion behind, because I stopped buying the print editions, and getting the .epub versions direct from j-novel.club made more sense. Now, though, I buy print editions of Bookworm books, and my usual supplier doesn't exist anymore, so...
