In EU no one individual needs to sue them. The what-ever-the-office-might-be-responsible at EU burecracy will just send them an nicely worded letter that says "play by the book or we'll give you fine big enough to bankrupt you no matter how much money you think you have". The fine is based on company revenue (or sales, I don't remember what it spesifically was) and there's no way you'll weasel yourself out of that no matter how many american lawyers you can hire. The same folks forced Apple to adapt usb-c, so good luck Spez if you try to challenge that.
