No, the issue here is that the Tesla App now allows you to buy a software upgrade package by just tapping through a few screens and the $4k package is added to your cart by default. They don't offer refunds (unless you're internet famous). Practically all other apps require fingerprint or password/code for purchases. Tesla doesn't - and their default checkout basket has $4k worth of unrefundable stuff in it, which is hilarious bad.
The EU/US is a separate historical issue where Tesla states on its website the cost of the vehicle incorrectly - the cost includes the federal tax credit (which you can reasonably expect to get) and $8k in gas savings (which is just a made up number based on random assumptions about how, where, when you drive). Imagine if BMW told you the cost of your vehicle including the gas savings you'd make versus driving a hummer. In the EU lying about the price of a product is illegal, so Tesla display the real price in the EU without their bullshit "savings".
