I think that the cracking groups could have released better explanations on how their tooling worked so that others could at least be closer to "up to date" with the current DRM technology. Right now public cracking info is years behind because the groups that did have any knowledge took it with them. The idea that this would help only denuvo was a bit myopic since either way when they left cracking it would help denuvo. However I heard that many cracking groups now work for denuvo so that may be part of it. But considering they did all that work for free, I don't want to conspire about them or claim that I am entitled to their work.

Edit: Also the people who have released "how to break denuvo" guides have been some of the more aggressively persued legally. So my lamenting over no documentation/explanation may be a bit "man i wish someone would break the law for MY benefit."

More people working on breaking Denuvo would mean more cracked games and more vulnerabilities being found. Even if Denuvo team could keep up with that, it would be extra cost for them.
