It's like we're not even having the same conversation. McNealy, founder of Sun, testified under oath that GPL doesn't permit commercial use. What was unclear about this the first time it was stated?
That is alarmingly false. Do you have a source that McNealy indeed has said that? I couldn't find anything by googling.
