Your example for the Union Jacks on meat [0] seems incorrect. They clarified that they don't plan to ban union Jack's on meat packaging:

>European Commission proposals on the labelling of pre-packaged fresh meat (from sheep, goats, poultry and pigs) will not prevent the use of the Union Jack or of other EU Member State flags.

And

>This is because – while the Commission has no intention of banning flags and other logos on pre-packaged meat – it does not intend either to propose making them compulsory.

That's a pretty solid debunking.
