The opposite of open is theirs
The Net as a medium is not for anything in particular — not for making calls, sending videos, etc. It also works at every scale, from one to one to many to many. This makes it highly unusual as a medium. In fact, we generally don’t treat it as a medium but as a world, rich with connections, persistent, and social. Because everything we encounter in this world is something that we as humans made (albeit sometimes indirectly), it feels like it’s ours. Obviously it’s not ours in the property sense. Rather, it’s ours in the way that our government is ours and our culture is ours. There aren’t too many other things that are ours in that way.
If we allow others to make decisions about what the Net is for — preferring some content and services to others — the Net won’t feel like it’s ours, and we’ll lose some of the enthusiasm (= love) that drives our participation, innovation, and collaborative efforts. So, if we’re going to talk about the value of the open Internet, we have to ask what the opposite of “open” is. No one is proposing a closed Internet.
When it comes to the Internet, the opposite of “open” is “theirs.”
