I have a 2012 asus s46c laptop. Replacing its battery is as easy as sliding a nitendo switch joycon into/out of the console. Other laptops from around that time have similarly easy to remove batteries. There’s no lack of know-how and I doubt making it easily replaceable is “more expensive” during production. Any company that solders or glues them must do it out of pure spite against the customers.
