I get that Hackernews is dominated by people working in software and software news, but as a part of the real economy (and not the stock market) it's actually not that large and Europe doesn't frame trade policy around it, for good reasons.
The US also doesn't support free-trade for economic reasons, but for political and historical reasons, which is to maintain a rule based alliance across the globe, traditionally to fend off the Soviets. Because they aren't around any more, the US is starting to ditch it. The US has never economically benefited from free-trade, it's one of the most insular nations on the planet. EU-Asia trade with a volume of 1.5 trillion almost doubles EU-American trade, tendency increasing, and that's why Europe is free-trade dependent.
