Welcome to international commerce and trade laws my friend. The companies that run these websites have to be based somewhere. If you want to find out more on why this is the way it is, you can read up on it here:

And as for free information, have you ever received the following notice when browsing any of Tom's sites?
"Error 492: Invalid Country: Sorry, it appears that the country you are connecting from: 'Not America', is not America. Please relocate to America and retry your connection."
Probably not. The information they give out is free. The computers they give out, on the other hand, may not be free in all countries.
