The difference between satellite and the internet
is that with that satellite you have some control as to where the signal ends up; the satellite is very clearly and deliberately hung in (non-national) /space/ and its ground station very deliberately set up just to feed that satellite and make that signal end up in a certain area. So there, it makes perfect sense to hand jurisdiction to the receiving end. The thing was set up that way.
On the internet that is just so much wishful thinking. The servers just sit somewhere and everybody else makes a connection to that server and asks for the information. Though the ease of crossing borders with those requests and their replies is making those national borders more of a nuisance and legal fiction than something anybody else really cares about. Right up until you need to make the law do your bidding, of course.
You could argue that with your servers set up to only allow access from certain countries you could create a situation sufficiently similar to satellite, but it's a much less exact science and with a lot of on-going work to subvert any restriction you impose there, too. Though I usually use "who has control?" as a yardstick, filtering as a legal argument is something I'd rather stay well away from. You also (presumably) have control where you put your servers and that's a much simpler legal yardstick, for one because it takes much longer to move servers than it takes to change filtering rules.
Virtualisation is gnawing away at jurisdiction there, too, so we might end up having to simply declare nationality and thereby jurisdiction of the hosted services and content eventually, but that's not relevant to this case, hopefully.
The nationality of the author or the jurisdiction of where his desk sits isn't at all a better substitute, simply because there's not necessarily a ready record of that, and even if there is it might cause lots of impractical conflict. Think china claiming jurisdiction on facebook servers because some dissident wrote things on it they don't agree with. Can they even prove the dissident wasn't in some other country when he published that? Or is time of publishing not important? Again, as you try to pry the proposition apart, soon you ought to notice that the notion is not tenable.
