Sounds like another case of US tech companies fucking with the web of EU regulations to nobody's benefit but their own.
It's no wonder they moved to another tax haven. Sorry, sorry. The EU doesn't have tax havens according to their own rules. Low tax threshold geographic jurisdictions.
Apparently, according to that link, they did try to class Ireland and the Netherlands as "countries with traits of tax havens" but the recommendation hasn't been implemented. Quelle suprise.
