Maybe in an abstract Reddit community kind of way. For paying end users I doubt Denuvo comes up much. It works behind the scenes and is pretty reliable.
Unless their games run slowly, or they can't install a mod/fan patch, or they want to play offline, or they hate having some third party snooping around on their devices and collecting their data.
The reason is simple: i want to have access to the games i bought regardless of Steam and when i buy a game there i also make a separate offline copy for my own archival. Denuvo - or any DRM really - makes that impossible. Fortunately most games (like pretty much all indie games, which are what i mainly buy these days) have no DRM at all on Steam and the few that do make enough of stink for me to know and avoid them.
So yeah, Denuvo is reliable for making me ignore a game (until it is removed at least - amusingly enough that'd often be after a bunch of patches have been released and the game had a bunch sales/price drops)
I'd probably buy a game with Denuvo if i REALLY wanted to play it (e.g. i bought Prey 2017 despite Denuvo) but i'd do that only after the price has dropped to "sandwich levels" (e.g. i bought Prey 2017 at a handful of dollars). Note that i also put money where my mouth is and when a major game that i want to play is released on GOG (which has DRM-free games) i do buy it full price or close to full price.
Could you let me know which curator it is? I'm also actively avoiding any game that uses Denuvo, so I'd certainly find such a curator useful.
That some platforms more aggressively inform you about these facts is very appreciated. Same applies to some rootkit anti-cheat software.
Denuvo has often been the cause of these issues and less technical players will usually direct their annoyance at the game publisher (which is ultimately the right place) but they won't know to attribute it more directly to Denuvo itself.
