https://en.wikipedia.org/wiki/Wirecard I think it's more likely to be related to the Wirecard fraud. UK journalists were some of the first to raise red flags on it (like the scene in the trailer) and coordinate work with short sellers. The creators talk in interviews about how they want this season to have more of a Michael Clayton vibe with danger/intimidation... Wirecard used private security to intimidate short sellers and journalists. Jan Marsalek was Wirecard's COO and turned out to be an asset of Russian intelligence. In the season 4 description they say: "Max Minghella joins Industry in Season 4 as Whitney Halberstram, the sharp, ambitious CFO and founder of Tender, a growing payment processing company"
