User choice is a problem. It’s one that platforms have been tackling in different ways for decades now, and it all comes down to a balance. Users want the freedom to install whatever software they want. But the companies behind those platforms understand that they also need to keep their users protected against the threat of malware. So how do you keep that “do whatever you want” door open, while also employing a bouncer to keep the peace?This is as much a technical problem as it is one centered on human behavior, and that messy human part of it means that there are always going to be edge cases where one-size-fits-all approaches don’t work. But with that acknowledged, Google’s new “advanced flow” for sideloading apps strikes what I think is an incredibly satisfying compromise — and this 24-hour delay is probably the smartest part of it.
