I actually did read the entire article. Most people seem to be reacting to the title, Arduino clearly attributed Wiring, they didn't just steal it and not say anything:
34. Banzi is the creator of the Programma2003 Development Platform, a precursor of the many ARDUINO-branded products. See: http://sourceforge.net/projects/programma2003/. Banzi was also the Master’s Thesis advisor of Hernando Barragan whose work would result in the Wiring Development Platform which inspired Arduino.
This was probably written by a lawyer and not Massimo himself. Its a legal filing. It says clearly Arduino is inspired directly by Wiring. What else do you wan't from an attribution of credit? Should Massimo get a tattoo that says "Wiring" on it and put it on his forehead?
