These programs should have been blocked by the EU before entering into force. When you're part of a free-movement union, you shouldn't be allowed to create such programs without the consent of at least a majority of member states (maybe that did happen and I'm just ignorant to it), since otherwise you are unilaterally making immigration policy for the whole EU.

On the other hand, the free movement union might have taken significantly longer to establish if it started with "all citizenship and immigration laws are repealed and from now on all citizenship and immigration decisions are going to be made in the European Immigration Agency in Brussels". The EU started loose and aims for closer links over time.
