It's not unusual to turn on a console and be greeted by a screen of pending downloads for games you have installed. It happened to me today. Several games needed updating, meaning hundreds of gigabytes of data to download. This didn't particularly bother me. I have an uncapped and relatively speedy internet connection. My primary concerns were exactly how long it would take and how much hard-drive space it would require. What effect all that data would have passing through the network didn't occur to me. I couldn't see it so I wasn't thinking about it.
Do you have any idea how much internet data you use a month?
