Well that is something that is very strawman like. However you don’t;t need “far leftist thought” to examine this. The academy are well known to have tastes and favour some types of movies over others.

The oscars has consistently ignored SF/F, favoured films about history. To the point that some movie makers directly pander to the academy’s tastes in an attempt to get a Oscar nom.

The academy knows that there taste is out of touch with the American people because the movies that gets Oscar noms are less and less like the movies that American people like. This is a part of their attempt to fix this.
