On the other hand, before the iPhone, literally every phone had a back cover that could be removed with bare hands and batteries held in by friction. After iPhone, all phones are sealed and require tiny screws to be removed, special adhesives to be defeated (god help you if you break off the stretchy adhesive strips), and of course seals to be replaced. And all this was done from the 2007 iPhone, over a decade before Apple did any IP67 rating of any kind, so none of it was done for waterproofing.

So, "Apple killed battery swappability" is a fair thing to say.
