That might be true, but it’s also the reason we don’t have a Zuckerberg or Musk taking charge of EU politics. There’s a balance to be struck here, and I prefer this over being a slave to American big tech.
There's benefits, but there's a LOT of cons that people refuse to admit, and this is not saying "brexit was better", just that EU politics are riddled with corruption and pretending we're good because we try to compare ourselves to a different context in the USA is just pointless.
