How to voice disagreement over S&P500 inclusion rules change for SpaceX?

S&P500 and other index funds are evaluating changing the rules for including stocks into the fund. There are multiple rules that might be dropped: * 12 months of trading * 4 quarters of profitability * at least 10% of stocks tradeable

The effective result might be that IPOs from Space, OpenAI and Anthropic result in their stocks being added to index funds, and thus automatically bought, without a chance for the market to set the right price.

Basically regular passive investors and pension funds would end up holding the bag in case the IPO is overinflated.

Exiting the fund makes no sense, as you'd trigger capital gains, so we cannot reasonably vote against this rule by exiting the fund. We can stop buying it, but that is a slow signal against the change.

Is there something we can do? Write to S&P? Write to the SEC? Write to our broker/index fund provider? Are there other actions we can take so we don't go in the direction of rich people forcing regular people to buy their investments?
