A major point of contention amongst the non-eA-market BEMANI community is a unofficial implementations of eAMUSEMENT for machines outside of Konami’s markets.
On one hand, it’s pretty much a blatant breach of copyright; Konami did not intend for their services to be duplicated and their games pirated. But on the other hand, machines on these unofficial networks are often in public. It’s not like you need to take a 5km elevator ride down and go through ten blast doors each with authorization measures to play on such machines; anyone can walk into, say, Sunnyvale Golfland or such and play on these cabinets that are not running official eA, and if they have an eA pass they can see the address for the network’s web interface (which replaces the official eA URL). On top of that, Chrono Seeker is translated into English, and anyone with a pass will see all that delicious translated text. That’s an unofficial fan effort, not an official localization.
Tau himself has stated that Konami doesn’t really care what goes on with BEMANI cabs outside of their markets, because it doesn’t affect them. It’s when, for example, Spada Omnimix screenshots or obvious home setups of arcade IIDX games make their way around Japanese and Korean communities that it becomes a major issue.
Finally, as my friend says: Piracy is a service issue. Why are such networks implemented in the first place? Because we want a way to experience these various online-only goodies without having to travel to Japan or other countries with eAMUSEMENT. If BEMANI games were released for the international market and eAMUSEMENT was an international service–two things that I highly doubt will ever happen–this entire discussion would not exist in the first place.
