Yes, Blizzard could shut down a wide number of private servers hosted in the EU in the near future. Including this one, since it's hosted in France. It all depends on if this thing is passed and recognized by the EU trade union and the USA.

France, Germany, and the UK would all roll over and kill servers once freshly printed C&D's were issued.
Nations not a part of the partnership would continue to give Blizzard the middle finger. CZ is one of these.
If Trump OR a Democrat gets elected, this thing will pass for certain as far as the US is concerned. It will be on the EU nations to see it through at that point.
