TBH I see this as a positive - less weight on the plane, less fuel consumed, less waste when these screens are junked, etc. I personally always take a ton of videos with me and just watch my own stuff, I would never trust that the in-flight stuff is working (although I admit I overprepare and it's still important to provide this). And when you're flying - having the app installed is a net positive, it has maps of the airports (with great directions, which is super helpful when you're making a connection), can manage your ticket, etc - the videos are a bonus.
