Very wrong, if GW claims ownership of a copyright to their IP, then it is their right to protect that IP, much the same Marvel would sue you for publishing and selling alternative stories of Spiderman or the X men. It has to do with CH PROFITING from the sale of this copyright infringement, not the generation or production of it. I can make alternative Spiderman stories and drawings all I want, but I can NOT profit from the likeness of Spiderman and/or his themes. That is how copyrights work, and helps protect professional artists such as myself. CH has every right to create mods, but they have absolutely no right to profit from them.
Only so long as the mods specifically reference Spiderman.
Perhaps this might clear things up, since I'm among those very recently acquainted with this whole mess: Just how much of Chapterhouse's stock was deliberately named after, designed based on, and meant for 40k? After all, the 40k universe is so broad that any number of designs for the same weapon, bolter, lasgun or otherwise, could all apply. Same with the infamous Mycetic Spore: What if it were renamed to "Alien Invasion Capsule"?
If CH was using GW terms, symbols, etc. then they're clearly in the wrong. But if GW is going after them because they were making guns, clothing, and equipment for miniatures that just so happened to be the same scale and proportions, how could GW possibly be in the right?
Now as far as my own observations are concerned: Their website may be shot, but their facebook page is not, and it's hit and miss. On one hand, the names of their creations are predominantly generic. On the other, they flat out reference Space Marine Terminators and White Scars. They also use the White Scars symbol, and even have an Aquila on a belly plate. Going further back shows a kickstarter 'entirely predicated' on 'compatibility' with "Necrons, Tau, and Eldar," without even the pretense of wide-application by referencing other tabletop games, settings, etc.
I think this explains everything in a nutshell, including the sweeping legal victories CH saw prior: Their tendency to harp on 40k applications, and occasionally use directly ripped symbols, damns them. But not all of the time
. And yet it's like watching someone with multiple personalities: Can't make up their minds.
It's kind of ironic, in a way. In both cases, both companies have a lot going for them, and then some series of decisions from high up screws over everybody beneath them, from the workers to the players. Chapterhouse already garnered attention having made these (apparently quality?) ripoffs in the first place, so why couldn't they just let it die and then ride that new reputation into more varied and worthy pursuits? Similarly, GW finally found a target justifying its rampaging IP protection policies, but is liable to win in a way that utterly destroys CH rather than grant it room to reform (admittedly debatable due to the length of time).
And you know what they say about "Those who live by the sword..."
