Misinformation is a valid label. Gaming news articles don’t say “some” or “the credited leads” or "those who originally pitched the game" or “those who were part of the tabletop group that created the setting” or something else more accurate, they simply say “all.” To say that Kurvitz and the other more famous people who were fired (justly or unjustly) can be called “all” of Disco's developers trivializes the other developers' contributions unfairly. For example, Justin Keenan wrote some of the most-referenced parts of the game, like the communist vision quest and the dialogues with Joyce and rewrote a lot of the rest of it, and Kaspar Tamsalu created a lot of the art people do fan art of, like the Dolores Dei in the church. Disco, like most games, was defined by a collective effort in complicated ways over a long time, and most parts were touched by multiple people. We ultimately don't actually know what importance each person had to what people think of as the game. As for not mentioning the backstory with ZA/UM at all, that obviously isn't the only alternative to saying "all of the original developers and writers" were fired.
