It's not real content or writing, and really disrespectful of others' copyrights.
Not necessarily, especially after panda.
Imagine that you sold widgets of all shapes and sizes, each widget is powered by a common component.
You have carefully written an informative description for the square widgets power source but now have to think about the other 20 widgets that are driven by this component.
You either copy paste and risk the wrath of G, or try and make each product description unique.
