Had a battle on this blog about the heading: Turks don't need EU visa's anymore.
Anyway, this person is going on and on.
I can tell from own experiences that it is not so simple as he now is saying that in fact everybody can start up a business all around the EU. Let me give one example: I went with Turkish top orthodontists to the Netherlands to look for possibilities to establish a practice there. The EU ruling in this is simple: you have to learn the language of the country where you want to practice.
The ruling of the ECJ is in fact very simple and can be read here.
If you want the full arrest, take a look at this, and you have to read only the points 50, 54 and 57. The funny thing of the whole ruling is that the European Commission supported Veli Tum and Mehmet Dari, the two Turkish nationals. Since they want to uphold the European treaties.
The main goal of Ankara agreement (and additional protocol): integration of Turkey in Europe. With the acquis communautaire as binding factor. The chapter free movement of persons is not even opened for Turkey.
