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.

From how I understand the judgement. Yes the postal company does have a legal obligation to deliver to all businesses. In this case, it’s not the postal company making the decision to not deliver to Tesla but rather the union. Therefore the postal company is unable to make the deliveries due to circumstances outside of their control.
