You just happen to agree with this one, so you find reasons to justify it like "exercising judgement".

What if they exclude a company because of political ties to communist regimes? Or ESG concerns? To me neither of these is acceptable. I would be pretty annoyed if Exxon was excluded from SP500 because they contribute to Global Warming.

Go pick another index is not a defensible position when I'm criticizing the index's policies specifically. Yet to hear good reasons for why a committee "exercising judgement" is a good thing for the average investor.
