Intent is very hard to prove. In my last Sony laptop the keycaps were held in by hooks formed from a thin metal sheet. After a while (2.5 years in my case) the hooks start to break and the keys fell off. The keyboard was riveted and glued into the case which made it impossible to fix it. Was this the cheapest way for Sony to attach the keys to the laptop? Maybe. Did it get me to replace my otherwise perfectly fine laptop after 2.5 years? Certainly.
