Your first point is fair, though, again, you can't completely ignore the utility these services bring. And while it is possible to have Cloud-less alternatives, not everyone is a Hackernews type person that can setup local opensource alternative on a linux box in their spare time.

Your latter point doesn't really make sense. I'm fairly sure all of these devices use encryption to the cloud, it's just that the NSA has access to the unencrypted data on the cloud itself, theoretically. Unless you mean storing your own encrypted data on the cloud, which again goes back to the point above.
