Compared to that 3D Remake thingy's C&D, this C&D really, really looks incredibly... fake.

I mean, seriously. Just compare them. Crimson Echo's C&D doesn't have any lawyer's backing, any substantial copyright information about Chrono Trigger itself... it just cites some sort of valid DMCA laws which can be found *anywhere*, and looks like it comes from a real address, which probably isn't hard to fake.
I assume your complaint is that there aren't any SE names on the letter; just "Legal Department." That's because they anticipated the backlash that is now underway and don't want to deal with the angry calls and e-mails that they would undoubtedly be getting if they had identified themselves by name. They'd much rather that the community's attempts at communication be routed harmlessly through their front desk into the round bin of the PR Department.
Frankly, the whole lot of you are greatly overestimating the pedestrian nature of corporate communication. Not every corporate document is a flowing fountain of literature, printed on sheep's parchment and girded into a gold-embroidered envelope with a wax seal. In fact, that kind of glitz rarely exists outside of a PR context. Most corporate communications are lame, ugly, rife with grammatical errors and structural deficiencies, and sophomorically worded in an attempt to be clever without really having the chops for it. We're dealing with a room full of worried individuals who recognize they have ignited a groundswell of contempt for them and their company. Their desire is to move the situation forward on their terms. They put out an anonymous C&D because it serves their interests.
I know that's pretty hard to swallow. I wish I could tell you more of the details, but that's not my decision to make. You don't have to believe the Compendium; you don't have to take us at our word. Belief is a dangerous thing in any case. But unless you have hard evidence to prove your case (which you don't, because you're wrong), then I suggest you go to some other site to spread your insinuations. You're not going to get any support here, and, if it were up to me, this kind of rumor-milling would be fast deleted.
