At the time, yes. But not for years now. Apple could've changed the path by opening this as a standard but choose not to.
> Imagine if we mandated microUSB in 2010.
Apple would include an extra/expanded connector like a number of other device producers. Then they'd talk to the other large companies about moving to a new standard just like the currently introduced law proposes. This is not a "you must use usb-c" law, but rather "you must figure out how to get along" law.
Also, this pretty much happened, just without regulation. EU at the time effectively said "figure it out, or else" and microUSB became a standard for years. Now they felt like they need to push harder.
