You need to understand that this is not a bug, it's a feature.

Quite a while ago when I submitted an application to the store, it was my decision where I wanted to make it available. I can imagine there's reasons for publishers not to make content available world-wide. (A local shop, bank or TV station might not be interested in receiving support questions from around the world, only to tell people that the application isn't intended for their use in the forst place.)

Also, payment methods play a role. If you don't have a credit card and operator billing is not available in your country (see this map), then that was it.

It's not usually people at Nokia who are responsible for this.

Of course, as don_falcone said, the whole concept of an app store is broken.
