This is the famous Japanese business model? Make your product unusable by the people that want to buy it?
This is the same crap you did when you broke the PS2 update thing. Your answer to that was to have your customers repair the damage that you did. That's what they teach in Japanese business school? I'm confident that your answer to this will be to ask your customers to jump through hoops again. Is this making sense to you? Are you not noticing your shrinking client base? Do you really think that your customers are going to keep putting up with this? You are currently planning a mass server merge because of your clients leaving and your answer is to keep making your product unusable and then asking your remaining customers to shoulder the responsibility for repairing it. This is absolutely mindboggling to me.
