That depends. Closed doesn't have to be 'evil', but open almost never is. So even if there isn't a 1:1 correspondence between the two you'll be finding 'evil' (lock in, proprietary protocols, overpriced hardware and so on) invariably when stuff is closed.
But of course there are manufacturers of closed source that do not do 'lock-in', that open up their interface layers and protocols and that price their hardware reasonably.
edit: I really just have a nitpick with the tossing around of the term "evil". It's almost as if Godwin's Law should adapt to cover not only Nazi comparisons, but also absolutes of morality.
