English being just one of the official EU languages would not have mattered much. No one is picking up Portuguese or Polish, even though they are also official languages and have been for a long time.
The important fact is that English is the lingua franca of both trade and administration in the EU. People sometimes still learn some French and German, but the vast majority of international EU discussions are in English, both in the EU bureaucracy and in business circles.
