The European Court of Justice still has to rule on the matter (from what I recall) and the Advocate General's opinion is just that. However the fact that it specifically mentions a "legal construction" created to obtain a .eu domain in contravention of the regulations has probably put a lot of the industrial level cyberwarehousers' .eu domains at risk if the ECJ confirms this. Interestingly Dotster dumped about 20K of its warehoused .eu domains at the end of April. However .eu is a dead zone to most EU people and businesses. The EU domain market has a .com/.ccTLD axis and those two TLDs often represent about 80% or more of the domain market in each EU country. Again, if this opinion becomes a ruling, then theoretically any proxy registration within .eu (and potentially other EU ccTLDs) is at risk.
