> Personally, I like this proposal

It is meant to be a popular proposal that will win lots of likes for the EU, but it's stupid on the face of it and it will end up comically abused. E.g. companies could create 2 resellers across europe, split the revenue and avoid the tax. It's not less brazen than their current dodging schemes and it just shows the impossibility of taxation under global free trade. It's also very passive aggressive, if they wanted a tariff they should impose a tarriff.
