They weren’t all-in or first because they refused to add them to their mobile products until years after everyone else. They fought tooth and nail against integrating it into the iPhone until the EU forced them to. It’s well documented. The MFi program - namely the associated accessories - was very important to them.

Putting USB-C on their laptops in 2016 is a different discussion and it wasn’t a tough decision because none of their computers had lightning integrated into it anyways. If anything we should be asking why they did that and then took 7 years to put them on their phones. They could’ve had one port for literally everything since 2016 and yet the EU had to force them to do it.
