That's true indeed (those were also the people who told us Shirley Walker was really the one who wrote Elfman's scores, that he was incapable of doing it on his own, etc. Riiight....)It used to be you needed to have some actual schooling in musical forms and theory to get a studio gig, but now all you need to do is fetch Hans Zimmer a cup of coffee. Evil or Very Mad People used to give Danny Elfman crap for being a "hummer", but all of his music is legimately written down, instead of just improvised at a keyboard.
Film music today -- a lot of it isn't even "music." It's not coherent, developed thematic material -- it's just wallpaper with "riffs" and rhythms. Paul MacLean linked to an interview with Horner where he said they don't WANT THEMES anymore -- it's too "old fashioned."
If they think John Williams STAR WARS score is old fashioned, they've lost it completely. A 10-year old tinkering on a keyboard is as "artistic" as most of today's film "music".
