A top EU lawmaker argued Tuesday that U.S. tech giants should be regulated by the EU country where they are based.

This means that Google, Apple and Facebook will be regulated in Ireland, as they have their European headquarters there, while Luxembourg will regulate Amazon.

This is in line with the country of origin principle enshrined in the draft rules known as the Digital Service Act (DSA), arranged by EU antitrust chief Margrethe Vestager.

Lawmaker Christel Schaldemose, who is Parliament’s rapporteur on the DSA, has indicated her support for the bill. She plans to go a step further by introducing a ban on some targeted advertising in the DSA, with the lawmaker expressing optimism that she will finalize her draft with other lawmakers before the proposed rules are implemented in 2021.

She clarified: “Targeted advertisements that are based on your behavior on Facebook, for instance, that should not be allowed. Advertisements based on the fact that you have visited websites for buying shoes and things like that, classic commercial advertisements should probably be allowed.”
