They are operating a business.
This is how business works.
If you are negotiating a deal with a business partner, you do not shit talk your partner to your customers, whether or not they deserve it. They are your business partner. You owe them respect.
Yes they can communicate with us, no they are not obligated to. I don't care if you spent $0 on their game or $200; unless there is something specifically wrong with your purchase they do not owe you anything. Everyone seems to think they deserve the inside scoop on development and business decisions with the advent of Kickstarter. You don't. It's a privilege, not a right.
The lack of communication that has always been the most troublesome is that between the Japanese devs and Nutaku and us. They (Nutaku) seem to know little more than we know about the game updates. They can and have lobbied for us, but that's about as much as they can do. That is ALL that they can do legally until they obtain developer control.
I've seen the way Nutaku runs the games that they have control of. I think their communication is more than adequate. They're not a perfect business, there are many things they could improve on (Compensation for stamina bugs in FKG comes to mind; but overall I am enjoying FKG) but they are providing what I feel is an excellent service at a more than reasonable price ($0). If you disagree you don't have to support them. But right now the holdup does not seem to be Nutaku, even though they are the easiest face to blame (and the only one that might actually respond to us).
