“Sideloading” is the perfect word to frame the behavior of downloading apps in a negative light or as an illicit activity. No-one has ever talked of sideloading an app on macOS – because sideloading is simply downloading an app from the Internet as we have known it from the very beginning of the Internet. I still cannot believe most people adopted this word as part of this discussion and keep using it, helping Apple’s narrative. Stop using “sideloading”, use “downloading from the Internet”!
