> Restrictions on how private parties can provide a private service are ubiquitous in every market...

I'm speaking more about "ought" than "is" here. I don't see any reason why Facebook should have to choose between serving everybody, regardless of the regulatory burden that it places on them, and taking a hike from the global market entirely. I'm not saying that they won't be forced to do so anyway.

And yet, they've probably chosen it all the same. In the hypothetical scenario where somebody has a metaphorical (or literal) gun to somebody's head, forcing them to use Facebook, I don't see how Facebook themselves can be blamed for this, and simply chalking this sort of thing up as a "negative externality" and saddling Facebook with the burden seems to be weaselly way of making Facebook to the will of somebody who just can't bear to give it up.

You can't always get what you want. Some of us would do well to internalize this a bit.
