Commercial interests and national ambitions mainly. Some corporations found it much easier to sell to specific EU countries than to lobby the EU, so deals were made. Also, the EU is more keen to protect privacy whereas specific EU member states want (to sell) free reign on their citizens. This lobbying game plays out all the time. You just cherry-pick your targets, find the weakest link so to speak. In this case, he more authoritarian and neo-liberal the parties in charge of the country/region, the easier you will net them.
