“homogeneity” I think misses the point of principle for what drives EU legislation. equality of opportunity, equality of access to markets, reducing reliance on monopolistic services, levelling of opportunity entities outside the US to compete in software/digital markets are part of the motivation; but probably most of all what drives this is steering tax revenues back the communities who earn and then spend increasing amounts of income on digital products but who continue to expect their political leadership to provide and maintain roads, schools, health care systems etc, but struggle when entities like Apple, MS, Google, Meta, et al become mega corporations that avoid tax payments in spend nations?
