Um... gotta say in context that sounds highly hypocritical. "What George did was wrong. I'm going to do the same thing, but it's cool because... well, I'm doing it and nobody's complaining about it." Pff.

Gaffer, I see what you're saying, but there is a difference. Lucas is adding scenes or special effects that are from the present day to a 30 year old movie. Cameron is just adding stuff from the cutting room floor.

If Lucas just added the Luke/Biggs scene by the X-Wing fighter in Star Wars, I don't fans like us would have really cared. It was a shoot in 1976, so the scene doesn't stick out like adding Hayden Douchebag Christenson to the Return of the Jedi ending, or a ridiculous CGI Jabba to a Star Wars talking to Han Solo.
