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.<p>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.
