They are not even shy to compare their plans to China's great firewall. Goes to show that free speech and democracy has never been and continues not to be a European strong point.
Such studies are usually intended to give external legitimacy to pre-decided internal plans. So someone had them draw up the study, telling them what the conclusion should be.
There's also the opposite effect - that organisations pretending to be legitimate create "studies" to shift the Overton window a bit. In practice, most of these things go into the circular file anyway. If you go searching on pretty much any topic, there's pretty much all the possible opinions in the form of "studies" for the EC.
I think the point of this would be to protect the EU IT market from American IT monopolies. Because currently EU is completely dependent on the USA when it comes to IT software and architecture, which is becoming a real problem. China's firewall has been a great success in that regard.
