These changes go against Apple's business model and practices. Forcing USB C will mean they will probably try to add some bullshit software check to their plug in devices so 3rd party hardware makers will once again be shut out. These practices allow Apple to tell their current consumers "don't buy 3rd party stuff. It isn't made well and won't work on our incredible phones". Will that get struck down in the EU again? Probably. Will they make a few billion dollars before it does? Absolutely.
Apple has purposefully avoided moving towards industry standards so they can keep everything in their control. For better or worse, it's actually one if the biggest strengths of Apple products. I know if I buy an iPhone, it's going to work great (until the battery goes), and any of their add on parts are also going to work great because they don't have to design drivers for the 400 different options out there. But that same practice inherently leads to these sort of anti-consumer decisions. Where a decision goes from keeping-in-their-wheelhouse to have-them-by-the-balls.
