It does seem like a bit much, but it's definitely better than the former state where none of that stuff existed, as far as Hollywood was concerned. I imagine it'll equilibrate over the next few decades.
Casablanca is just one example of a very great movie that actually was designed by a committee and motivated more by a political message (supporting the US entry into WW2) than artistic consideration. Contrast with an atrocity like "Heaven's Gate", referenced in TFA, which finally convinced 1970s Hollywood that giving some wunderkind-auteur free reign to follow every artistic whim does not necessarily end well.
