This is very strange. This sounds like something that should be settled in the courts; I can’t imagine a lawyer would recommend making public claims like this while lawsuits are pending.
A judgment has already been given, which Frogwares lost.
The judgment, in october 2020, said that frogwares had illicitly tried to end their contract with Nacon. They were condemned to pursue the contract. Hence Nacon has published the game as it was the object of the contract.
Frogwares was ordered to continue the contract while it continued to be litigated was the ruling I read. If Frogwares is in breach of a court order, the solution is to file a complaint with that same court that the order isn't being fulfilled. It almost certainly was not the court's intent that Nacon bought a copy at retail, made changes to the game, and published it under their own name with no attribution to Frogwares.
Their issue doesn’t seem to be with Nacon publishing the game though, but trying to appropriate their IP and even releasing other products without permission. That sounds like a clear breach of contract.
Case is already over. Nacon won. For better or worse, the developer is trying to win people over to their side on a case that was already decided.
I understand the huge frustrations they must be feeling, and they have legitimate complaints. But trying to rally public opinion against a publisher over a suit they lost is not going to make it easy for them to find publishers in the future.
It is most certainly appropriate for a victim to rally public opinion and raise awareness if someone acts maliciously taking advantage of the [therefore, broken] legal system supporting them. If the situation is anywhere near to what Frogwares claims it to be, it’s most definitely worth public attention and outrage.
That said, to me it seems so far that it’s one of those “another country, not my problem” cases. Publisher’s in France, developer’s in UK (or Ukraine?)—even if game developer has the money, best of luck suing cross-border, especially in current times.
This all seems very amateurish.
