Here is the GoFundMe refund form if you feel you donated to this campaign in part or in full based on the misrepresentation that no cease and desist letter had been sent by Fizzer to initiate the fight:

An Activision win can kill the game, not fix it.
The important part of this case is not whether Activision is able to register the trademark for "Warzone" (the word) in video games in general. Warzone doesn't need much to "win" here: they're fine if they can get the court to even say no one should be able to trademark "Warzone" (the word) that broadly, which even Activision's own arguments sort of lead towards. They can lose the rest of the case- the court could find that Activision does not infringe Warzone's trademark (because they pretty obviously don't), that Activision should get to trademark "Warzone" for FPS games, that Warzone can't trademark "Warzone," etc.- but still be fine as long as Activision doesn't get this broad trademark to a common English word used by dozens of video games before them and as long as Fizzer isn't forced to play Activision's legal fees.
With competent counsel and sufficient funds, Fizzer should be able to pull this off. But if he doesn't, then we're looking at an existential risk: Activision owning the "Warzone" trademark means that Fizzer's apps and search engine listing either live at Activision's mercy (even though the law would probably grandfather Fizzer in, this process would be going through kangaroo courts run by Google and Apple- and if you've use YouTube, you know those tend to side with the big guys more than with the law)
or he goes through a possibly costly and risky rebrand for his entire business. Either of those things could nudge this whole enterprise to the point where it no longer becomes financially viable to maintain such a generous, user-friendly game.
It's not the most likely scenario, but it should be an uncomfortably high risk if you care about this game enough to complain about it.
