European Commission spent 360,000€ on a piracy study, from the Dutch consulting firm Ecorys, whose mandate was to "research the effect piracy had on sales of copyrighted content" -- the report was completed in 2015, then buried it because they didn't like what it said
That's because the report concluded that "the results do not show robust statistical evidence of displacement of sales by online copyright infringements" with the exception of "recent top films."
The European Commission has gone on to institute and recommend a series of brutal, repressive systems of censorship and surveillance in the name of preventing copyright infringement, stating all along that this was necessary to preserve the arts in the EU.
German Pirate MEP Julia Reda discovered the report on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard.'
