I'm not sure how they are related. USB-C was not really a technical challenge or had trade-offs. I'm not a hardware engineer but from what I've read, having an easily replaceable battery would degrade the water resistance of the phone.

Don't get me wrong, there were plenty of people in the more toxic parts of Apple's fanbase decrying USB-C for appearing too fragile, for being forced on them, for having a confusing set of standards (that last one is a fair point).

But I think, among Apple fans, USB-C has generally been a point of 'pride' for the past decade. Designed by Apple, put in a laptop first by Apple, best $10 USB-C-to-3.5mm DAC by Apple, etc.

Whether correct or not, I think Apple fans anticipate more severe tradeoff ramifications with a replacable battery. I think they're different things. (I don't think it's impossible though- the Fairphone has IP 55, I bet Apple can improve on that).

The Apple Faithful will always defend whatever Apple does, it's not terribly useful to listen to them.

It's the Apple Faithful who criticize Apple that are worth listening to.

Lightning is a superior physical design to USB-C (can't speak to the electrical part). Much like every major tech battle in history, however [1], the worse solution won because of ubiquity. I'm not particularly thrilled because I've had a USB-C connector irretrievably break off in a port once on a laptop but I'll make that trade for being able to use a single cable for all of my devices.
