Why do you think it is an excuse? Does Nutaku staff translate the game or some people in Japan that work for DMM? Seeing as Devs are the ones who roll out the updates I believe it is the latter. Maybe they see that keeping extra people to translate the game costs more than the income that English version brings.
I don't understand why people are so angry at Nutaku. They brought you this game, without them you wouldn't play it for those two years because you wouldn't even know about DMM or can't play in Japanese. I am not talking about you personally, but about 95% of the people who complain. It is very sad to see the game gone, but it was a business decision, it is not a charity, you know. All this anger and personal assault at Nutaku are just stupid. It's like complaining at Steam that some developer closes down his game...
"Horrible censorship" is not because of they just want to do that, it's because there are certain laws in different countries. While in Japan it may be ok to display sex scenes with characters that look young, in most western countries it is not ok.
"Gacha handling" - not sure what's this about.
