> The website was accessible from Germany
That's something Germany could control much more easily on its own by putting firewalls at their borders. There is no reason for the site to go out of its way to block access from Germany, even assuming that they could do so reliably, which they can't.
> The explicitly offered worldwide service ("anyone anywhere")
Just like most web sites are available to "anyone anywhere". That's how the Internet is meant to work.
> There was a disclaimer directed at people not located in the US
Which is a very large group of people, most of whom are not in or from Germany. They're seriously complaining that the site reminded people that they need to take their own local laws into account before importing content from elsewhere?
