I don’t agree. Instead, a lot of people allow the install because they have no say in the matter if they wish to continue playing the game. Even if it weren’t effective, I’m pretty sure most people would allow the installation of some form of not-yet-proven-to-be-dangerous malware if the alternative is cutting ties and accepting the sunk cost (be it in terms of in-game purchases, proprietary file format, etc).
