The EU did nothing. When Apple moved away from the 30 pin connector to the lightning connector they promised they'd keep it for a minimum of 10 years since so many people were howling about the change. That was 2014.

So, let's end the farcical statement that the EU stood up to Big, Bad, Apple. The EU did nothing.
