I have to say, I'm fairly pessimistic towards Nutaku's future because of their many failings, but even I didn't expect them to attempt to validate these kinds of edits. Their guy in the Osawari chat and their support team both treated the edits like they were a problem to be resolved, but I guess the official company line is now that they are working as intended.
To say that they notice a significant negative reaction towards the edits, and then go on to say they won't announce anything about them and they're all as they should be is just absurd, and a sign that their already shaky business decisions can only get worse.
I haven't spent very much on Nutaku's games, but every time they say something I regret it even more.
