I'm sure I recall other people from Europe complaining about having to go through Robert White.
However, as for checking my facts, I used to subscribe through RW. Then you had the quaint notion that publishing the whole of an article in the magazine was unnecessary, and that you'd leave part of some articles only on your website. Of course, distribution via Robert White didn't quite account for this, and meant that in order to read the magazine I'd already paid for I had to phone Robert White each month (during working hours, of course) to get the password to get on to the site to read the rest of the magazine.
When this was raised on another list, you couldn't see any reason to change things, so this was one of the factors in my decision to stop subscribing.
Lenswork, on the other hand, manages to allow Europeans to subscribe to their magazine without any difficulty.
