Like I said, I'm like 99% sure that's the only reason.Their claims on the races sold in the DLC are rock solid. This shit with the "hyperspace" image are questionable. The official stardock forums you linked to only list a squarespace upload. After some searching the original source of this chart is Brad Wardell's twatter. Supposedly it comes from the court documents but I can't find it though the suit is a fucking mess with hundreds of documents and pages. Even if it was uploaded, it isn't necessarily claiming they invented this concept but could instead be used to establish that the alleged copyright infringing material is a derivative work.
I realize Wardell and some rancid cunt crossed paths in the Autism Holy War but I really don't think there's a connection beyond kicking an enemy when he's down.
"But Jaimas," one may ask: "What about the 1%?"
Look, the last time we were down this road, if you had told me, when things began, that we would have honest-to-god evidence that dozens of individual lolcows and power groups associated with each were actively involved with one another, to the point of willing to An Hero their careers for the sake of a whore whose sole accomplishment was a fucking Twine game, I'd have laughed and asked for some of what you'd been drinking. We know where that led eventually. So while I'n almost entirely sure this is just the usual assholes getting in their two minutes hate, I'm resolved to not really be surprised by anything in this autistic fuck-fest, and @Cubanodun has nicely surmised why.
