The wiki page you link to does say that.
Voters have been figuring it out. Turnout for EP elections has been falling steadily since the institution was first created:

From 62% to around 40% on average. People don't bother voting because the EP can't/won't actually do much except cheerlead for the EU itself and demand it does more.
This sort of story appears from time to time. The EP calls for this, it calls for that. Nobody pays much attention because these "calls" don't matter. The EU's laws can only be changed by the Commission, and EU law is made entirely in secret (unlike every other legislature in the world save North Korea). So there's little point trying to get involved or care what they do - EU law just "appears" fully formed and gets implemented without debate.
