While perhaps not as restrictive as some had feared, Android’s upcoming sideloading changes to reduce exposure to malicious apps are undoubtedly controversial. Power users are the most inconvenienced, either having to remember to go through Google’s new Advanced flow (complete with a 24-hour wait) ahead of time or push an app install over the Android Debug Bridge tool. While the latter is very powerful, it’s not particularly user-friendly.
I don’t have a problem using ADB via the command line every now and again. But between remembering where I put the executable, opening a terminal window, connecting a device, and pasting in the APK file path, it’s a bit of a chore. Booting up a small app on my PC to handle much of the legwork would be much faster.
