That's a fair assessment, absolutely. Not to say there AREN'T bad apples that have made their way into the offices of Imagineering.
The reported $450 million, however, leads me to believe that OTHER projects were partially funded through this Guardians budget. I think of how the film industry will take money from a production to fund another production simultaneously. Disney does/did this specifically with their films and Disney+ projects. And, in my opinion, one of the exact reasons why Bob Chapek has placed Kareem Daniel as THE centralized budget manager going forward. [source:

I know film/TV is a different beast...but that's the only way I can justify their reported over bloated budget.
