The JFTC states:
DeNA forced “Specified Social Game Developers” not to provide the games through “GREE”, by disconnecting the website links of the games the developers provided through “Mobage-Town” if the developers have provided the games through GREE.
The whole process sure wasn’t pleasant for DeNA and these are pretty severe accusations, but even though I am not a lawyer, that should be it for the company. Tech blog Penn Olson collected some comments from DeNA itself.
