UPDATE In a response to Kotaku, Denuvo debunks the rumors about refunds if games get cracked. He said the protection served its purpose as it keps Doom piracy-free during the initial sales window, and that id Software removed it for other reasons.
“The simple reason why Denuvo Anti Tamper was removed from Doom was because it had accomplished its purpose by keeping the game safe from piracy during the initial sales window,” Denuvo’s Robert Hernandez said to me in an email. “The protection on Doom held up for nearly four months, which is an impressive accomplishment for such a high-profile game.”
Just a quick note that id Software has issued a patch that removes the Denuvo DRM from its Doom video game. As TorrentFreak reports, this is the second game with Denuvo that drops the protection shortly after the game gets cracked.
Last month Playdead removed Denuvo from "Inside", that game was released in July but got cracked by CPY in just six weeks, making it the quickest Denuvo defeat on record. Doom came out in May and a crack from CPY appeared early September.
TorrentFreak speculates a refund policy is one of the main reasons why game developers are removing Denuvo after the game gets cracked. According to aonymous rumors, Denuvo charges "high 7 figure sums" to protect AAA video games, but the contract comes with a clause that enables a refund in case the game gets cracked in the first couple of months after the game's launch:
“I do want to explain what happened here. Denuvo Software Solutions offers a guarantee, if your Denuvo game is cracked within a certain time (3 months is normal), you do not have to pay for Denuvo. Part of claiming the refund is you must remove Denuvo from your game.”
In the case of Doom, Denuvo was cracked by CPY four months after release but since it’s one of the bigger titles, it’s conceivable that a longer period could still be eligible for some kind of refund. Ultimately, Denuvo claims that its protection pays for itself so when a game appears online too soon, it may not have reached its goals.
