I'm not sure where the anti CG sentiment came up, but I think we can agree we generally don't like CG in films that were made prior to the advent CG. But even Blade Runner: The Final Cut contains CG but we don't begrudge its existence because non CG versions exist.

The same could be said for Star Wars or E.T. But now even Spielberg now suggests it's kind of pointless to go back and mess with old films.

Anyone who dismisses the use of CG in modern films needs to see the featurettes on Black Swan or Zodiac.
