Well, as far as I know, it's just a joke - or the OP is just thinking out loud since it's probably from that country. That country is still far from allowing such freedoms, and the only thing I have heard recently coming from that country is that one person was killed by a crypto miner (electric shock), and that one illegal mining farm was discovered.

From what I know, it's just a rough date - and considering that Serbia still denies all the evil it has done in the wars against its neighbors, and still claims the territories of other countries in a project they now call the "Serbian world." (before Great Serbia), it would be insane to let them into the EU, especially with the problem of Kosovo and what they are trying to do in Montenegro.
