The article is in French and behind a paywall so I'm writing a summary here.
Everyone who can should give this a read because it goes really in depth into the inner relationship between the two and every info is coming from people still working in both companies.
Lock if old.
-Focus dropped Frogwares and replaced them with Cyanide for Call of Cthulhu because Frogwares choose to work with Nacon (Big Ben Interactive at the time) on Sherlock Holmes and the Devil's Daughter.
-Frogwares still wanted to work on a Lovecraftian games so they pitched The Sinking City to Nacon who greenlight the project
-According to Frogwares, Nacon was months late on their milestones payment
-In 2018, Nacon buys Cyanide which angers Frogwares because the only reason they're currently working with Nacon on The Sinking City is because Cyanide took over Call of Cthulhu. So they no longer trusted Nacon and their relationship was stripped to the bare minimum
-Nacon on the over hand is claiming that Frogwares repeatedly asked for commercial data which could be used by other publishers, thinking that Frogwares was trying to self publish.
-Apparently, the split on the EGS exclusivity money is also a point of tensions between the two.
-At E3 2019, Frogwares announce the Switch version of The Sinking City which was unheard of by Nacon at that point. So while Frogwares claimed that a Switch port was not possible beforehand, they seemingly worked on the port using Nacon's money and marketing for a version of the game they would see 0 cent of.
-According to Nacon, Frogwares withheld key elements (such as materiel to create in engine trailers) for the game's marketing campaign. Frogwares denies and argue that they delivered those elements to the American company hired by Nacon to create the trailers (which is now closed). Frogwares didn't want to directly provide them to Nacon in fears of them stealing the source code.
-Since there's very little communication between the 2 parties, Nacon and Frogwares are both publicly communicating on the game without concerting each others. Which leads to situation where Nacon had to cancel some announcement because Frogwares went public first. For Frogwares, Nacon spent significantly less than what was agreed to in their contract for marketing.
-In the end what really drove Frogwares and Nacon to justice was in regards to money owed from game sales. Frogwares believed that they were being ripped off of their royalties since Nacon didn't share financial informations which led Frogwares to break their contract with Nacon and remove every version of the game published by Nacon.
