I’m a firm believer that regardless of operating system that a warning message saying that installing something could cause harm to your device definitely makes people think twice about installation if they’re not tech savvy (AKA know more than the bare minimum anymore). It’s definitely intentional that the large companies responsible scare you away from doing the things you want because they want you locked into doing things the way they want.
I personally like to reserve “parasite” for the investors, the ones who will literally send you to court if you try to be human to your employees.
