so lucas now thinks it is okay to add cgi to indiana jones?

1. Who said it was CGI? The only comment I've seen is that it's a different matte painting. Whether the matte painting is done in the computer or not doesn't necessarily make it CGI.

2. Who says Lucas made the decision and not Spielberg? Spielberg made all those changes to E.T., so who's to say he didn't make this change to Raiders?

I agree that this is an odd change if it's the only one. Why do it at all? Maybe they wanted to see more of the sky, but that's the only reason I can come up with.
