This is another case where the "open/closed" image doesn't apply and only contributes confusion. It wasn't free to begin with --- though there are notable cases where that is in fact the case. There are many JS libraries and full web applications that are in fact software libre. It just isn't really any freedom the users can exercise due to the lack of application interfaces. If I were in the mood for an argument, I'd argue that with all the ugly SOAP and Java services users had more potential freedom than today.
