Even as someone who, for decades, has been convinced of the ineptitude of the EU (as well as corrupt, conniving etc you name it) even I'm not sceptical enough to believe this is wholly incompetence on their part. I'd like to be wrong though - I'd rather it was incompetence than any commercial skullduggery going on.
The Polish have been fairly strong on it (probably riding high after they and Hungary won in their case in the ECJ against the EU over how they recover tax):
