@BuyFromEU longer version of comment, that does not fit here: https://www.reddit.com/r/BuyFromEU/s/zAPqK9DpPw

@BuyFromEU this would have huge consequences, beginning from US companies being disobbedient, through siezing us datacenters and military bases, whole world switching to open-source and self-hosting, tech alliance of EU and China, EU federation, economic chaos not only in Europe, possibly more civil unrest in US, etc. most critical european services would recover in weeks or months, but the damage to US reputation and world economy would be emormous

of course the switch will never be flipped
