Backblaze is a company based in USA which provides Internet services. For its services EU customers are charged VAT based on their place of residence which is assumed to be the same as the one on credit cards used for payment: https://help.backblaze.com/hc/en-us/articles/115004487993-VAT-for-EU-Customers.
I'm citizen of EU member state and I've used several US based Internet services paid by credit card. In most cases I wasn't being charged EU member state VAT.
According to Wikipedia, place of supply of services provided by Backblaze is outside EU (it's not in exceptions) and therefore no VAT should be charged.
Why do some US based companies charge VAT from EU customers for Internet services and why others don't?
Where do these VAT charges end up? Does Backblaze (or Amazon) give them to individual EU members states?
