This is obvious and unimportant.
Of course companies dealing with bitcoins could be required to give information to law enforcement.
It's a jurisdiction issue here. Why would a Japanese company be "required" to give info to the American government? My guess is that they're ready to sell their clients to avoid a US crackdown (frozen bank accounts, bogus terrorism and money laundry charges, etc).
Obviously. And its the right path. A single company can not fight against the USA government. Its ridiculous.
Bitcoin can be very anonymous. It does not mean is always anonymous.
