You and I have clearly different ideas of what "quite normal application behaviour" is. IMO, if an application is not primarily network-aware (browser, cloud storage, online map, updating...) then it has no earthly business going on the network. What's more, even for those class of apps, sending any information home is - well, maybe not downright malicious, but definitely naughty. A flashlight application using the network smells fishier than a fish market.
