And you'd like to go say what they've made is worthless?
I'm really saddened to see such a lack of empathy. In life we procreate and create, offspring and projects the only chance our fleeting sparks have to last into the long night of eternity. We should always be charitable to others who've made something, that we may one day be judged by the same measure.
Empathy aside: how many operating systems (kernel + userland) have you written, chummer?
