You keep missing the point that it is the online extension of a U.S. based country. Where you are when you choose to purchase the products is irrelevant, you are still engaging with a United States business. What you’re saying would be true if Epic had a physical entity in the EU through which U.S. sellers would be selling their products, but that isn’t the case . Furthermore, the fact that sellers outside the U.S. have to apply for an ITIN underlines that reality. They have to abide by U.S. laws, not the other way around. People keep erroneously citing Apple and Steam despite the fact that they are no different from Epic in this regard.
The Nintendo example was already discredited, refund policy had nothing to do with their decision to opt out of Brazil.
Again, at the end of the day it’s up to the consumer to know what rights they do and do not have. I highly recommend they actually read up on how these laws work, what jurisdictions apply and the terms they agree to when signing up to use a service. This is the same when figuring out whether or not you want to purchase a product. The information is out there, clear as day. Don’t take my word for it or anyone else in this thread, go and actually look yourself.
I see you’ve edited your post to include more information. You are correct, lawmakers are looking for ways to get around the inherent nature of the online marketplace -which is a border-less market. That hasn’t happened yet though, and isn’t likely for some time if ever given the considerable resistance they are facing from giant online distributors such as Amazon who have significant sway.
