Ok, show me a "truly open" language that feels as nice to write, is as well balanced, and is similar technically to Swift and I'll consider it. As far as I know no such thing exists. This is why there's pressure from within the Swift community to improve cross-platform support and the number of use cases Swift is viable for rather than rallying around some other more open language, and I'd assume the same is true for the communities surrounding any corporate-founded language. People flock to these languages because they're filling needs that other languages don't.
