The more I think about it, the more I believe that the timing for this was not a coincidence. After years of silence, Amiga Inc talks now in a public forum all this previously private information (legal issues with Hyperion, OS5 in development since 2004, etc).
Their history has shown that they don't give a dime about the "community". I think they are using this forum for some reason. Maybe to send a warning to Hyperion?
