Companies can get away with price differences for physical goods, for a bunch of obvious reasons which don't apply to digital goods.

If someone voluntarily pays a "France" price rather than an "Estonia" price, you could achieve the same thing by setting up a pay-what-you-want cart with the Estonia price as the minimum. There are many sales tricks that can be used to persuade people to pay more (up to their willingness to pay), that would cost you nothing or next-to-nothing, to get more money out of customers even if they are only required to pay the Estonia price.
