Well, it could be good or bad, depending on how you look at it. It's foolish to argue that background tasks can't be useful. Can they also be privacy-violating battery drainers as well? Sure. I'm sure there's a right tradeoff here, and it doesn't have to be "no background tasks, period". My personal take is that it's much closer to "no background tasks" than "free reign", but your needs may vary.
