I don't doubt their intentions, but their execution leaves a lot to be desired. The Youtube app used to have a setting where we could make it only show videos only in low-res mode. It's gone now, and family members who are not tech-savvy use up a good deal more of the monthly download limit than they used to.

I'm surprised that it needs WiFi in order to share.

If your friend is already on WiFi, why can't he just stream from YouTube?

I miss watching all uploads of a channel chronologically
