From what I read in that topic at Studio Kagero, it seems this person was trying to bring down their fan projects, and because what happened with the C&D and Crimson Echoes and everything, the team at SK has decided to put a stop to all their work with their fan game.
This person seemed to be happy about that, even expresed his satisfaction to see that both CE and the game at Studio Kagero was going to a halt, but for what I can gather, it seems this person was really going after them, the people at Studio Kagero and Chrono Crisis, for whatever reasons s/he had...
Now, how valid this e-mail is, that's another question, and I am affraid I don't know the answer, it could be a fake, but the intentions of this person where clearly bad regarding the fan games, and s/he even expresed his/her ill will towards the modding community and how glad it was that SE took action against it.
In any event, I agree 100% with Enigma, this person is a complete asshole...
I am sad to see this kind of behavior, but I am keeping my hopes up for CE, for all the dreamers, our planet's dream is has not yet ended!
