Do they actually have a business presence in the EU?

If not, how would those rules apply to them?

Edit: tbh, the new "user friendly" idea of automatically converting US prices to the local currency of the visitor in spite of the company not having any connection to the visitor's locale always makes me think of drop shippers, not of legitimate businesses.

Especially if i'm in a non USD non EUR country, I am fully aware that there are different currencies in the world, I already have an established process for converting between those currencies and it's likely to be more to my advantage than whatever Stripe offers so please cut it down.
