Fair points. I was mostly thinking of situations like downloading using a separate device, writing to a usb drive or SD card and installing via that. Downloading an installer and using it is just downloading without using an app store.
I’ve always took side-loading to mean installing from local storage, as opposed to downloading from remote storage. As far as I’m concerned downloading from a third party app store should not be treated as side-loading.
