Where I'm working, all the dependencies have to be approved before use and are stored locally (build machines have no internet access), but I haven't found that the quality of the software is better than the other places where I've worked. I think it's more a matter of work 'culture' (not sure if that's the right word, perhaps expectations would be a better fit?), with the idea that we ship once it's good enough and that's it.
