He's a professional, Go-Mer. I know he says that. He's not going to say differently. Your quotes prove nothing.
I work for a Corporate Communications group. People/professionals who write and make official statements like that all the time, every day for people just like George.
Trust me, nothing that he says hasn't been polished, or he says little about it. He knows exactly what to say and how to say it - the PC answer.
Lucas is more controlling of his official statements than anybody I've ever seen. He's very reclusive, and almost every single interview he's ever given is pre-scripted. Usually, he's even written the questions that he wants asked before conceding to the interview.
His statements/quotes are valid when it comes to proving what he intends for a particular scene or the meaning behind it. But when it comes to something like 'catering to fans', he's not going to say anything but "No, I don't do that." Everything has a spin in his favor on it. That's the difference between professional and amateur.
