Why can't we download free apps from every region?

Hello all,

I am trying to get the full version for angry birds free, I know it is available to download, however when I do a search in the app store I can't find it.

When I do a search on google, I can find several links to download it, but when I do, I get a "this app is only available in the US store" error.

I don't understand why this happens in the first place, it are free apps, I can download them to my pc, android users can download them without any problems, so why can't we?

As for all the discussions about needing a different credit card for each region is a load of ********, excuse my language, a visa card or any other credit card is made for international purchases, that is the whole reason people get one, it makes no sense why apple is being so anal about it, or do they like o annoy people who spent a lot of money on their products.

Android is gaining on them and pretty soon a lot of people will change to that instead of an apple product unless they get their act together here.
