Applying the same principle to other rules would make for weird situations. For instance, let’s imagine a US business decides to make surprise changes to its T&CO and put penalties on some random behavior, but only applicable to EU users. It would proceed to take exorbitant amounts from EU cards, and refuse chargebacks pointing at the T&CO. Would it be completely shielded from any fines and lawsuit from EU users ? My gut instinct would be that even if the US company doesn’t have a EU presence, its service providers do, and a gov. could request any of them to recover legal fines on behalf of the country.
