The answer to your question is a quote from Lucas that I read in a hardback book covering the history of Pixar from around that time. He essentially said as much. Also, at that time, Industrial Light and Magic was a practical shop, they were not doing "digital filmmaking" and Lucas wasn't yet a proponent of digital filmmaking, as this really didn't exist yet. So, Pixar was very much an odd duck there, they didn't have shared backgrounds with the other groups and operate in a way that was difficult for the existing management to manage.
For the past 30 years I've been reading people denigrating Apple based on innumerable falsehoods and misrepresentations. Ever since the Apple II had competition, there have been fans of competing systems who felt the need to attack Apple, at that time, because it was the dominant system. During the windows era, because Windows fans felt vaguely insecure about the computer they were talked into by a salesman, and nowadays, by google fans because they want to believe that it is ok for google to rip off the iPhone and give away a counterfeit operating system. All of these people have both a motivation to denigrate Apple and, since they know that Apple is one of the few genuinely innovative companies in the industry, they end up having to make up stories to try and make Apple's innovations less significant than they are.
One of the ways people denigrate Apple is to pretend like there is really no difference in usability or performance of Apple products, while also claiming that they are more expensive (even when they aren't) and thus that anyone who buys them is obviously a victim of a Reality Distortion Field. For these people they cannot debate the purely pragmatic reasons that people choose Apple products, and so they attempt to portray Apple users as part of a cult, and often speak using religious terminology.
Ironically, it is those who talk about the "Reality Distortion Field" who have actually substituted ideology for pragmatism, otherwise they'd have pragmatic arguments to make.
