>It is not a synonym for downloading files to your computer system nor is it a synonym for moving files between two devices
Actually, it is:
"Sideloading describes the process of transferring files between two local devices, in particular between a computer and a mobile device such as a mobile phone, smartphone, PDA, tablet, portable media player or e-reader."

Additionally side loading refers to mobile devices not desktop PCs.
Yes, I suppose you absolutely can refute my point if you choose to discard the first half of my statement which specifies the scope.
Words can have different meanings under different contexts, and I'm providing you that context, which is important for understanding what people are talking about here. Please stop being obtuse.
You can just specify the scope as you like.
It's about Windows mot about Android.
Just because APK is an Android format doesn't change the context to Android.
