Since people are too stupid to realize that replacing the battery can extend the life of your computer for two more years, they're content buying phones and laptops with non-removable batteries. Because of consumer ignorance and their willingness to purchase devices without replaceable batteries, they're doing away with replaceable batteries.  It's very good for a manufacturer's bottom line.
