Now you know about web. Many (all?) people here (reading this shit) know. If you hear about what they are into, they are trying to get ''the next billion'' people into Their hands. Most of this ''next billion'' people don't have the time and/or courage to learn anything. They want to get their job done. (They will learn if they're forced to.)
What these big companies are trying to do is very clear. They don't want these fools to know much about web. If these people suddenly starts learning about how web works, that'd be a disaster (for Them).
Now, the address bar is just a distraction to them, nothing else. Now, if Google is removing them, let them. If the address bar is hidden, then there's less clutter. So, they'll think that it's better. (You and me know that isn't any better for us. I'd be really angry if they completely remove it.)
