They don't care because Apples batteries degrade much more slowly than others because of that conditioning software. And eventually you always have to replace a battery. Removable makes that a little easier, and a little cheaper, but the tradeoffs (lower capacity, more frequent replacement, worse build quality and packaging) aren't worth it for something an iPhine only need to do every 3 years in normal use.
