Suppose you had a index of 100 companys each with a market cap of 1 G$ for a total of 100 G$.You have passive investors owning 20 G$ of that index, amounting to 20% of the total, 20% of each company, and 200 M$ per company.
You then rotate out a company for a new one. The index is still 100 G$, but to match the index you are contractually required to sell your 20% ownership of the old company and are contractually required to buy 20% ownership of the new company.
However, the newly added company only released 5% of its shares to the public and the founder kept hold of the remaining 95%. Those fund managers are contractually obligated to buy 20% of the newly added company, but only 5% is available. Like a short squeeze, where the squeezer buys and holds supply so there are not enough purchasable shares to cover the shorts (obligated ownership), this is a financial divide by zero.
To get the remaining 15%, which they are contractually obligated to acquire, they must purchase from the founder. As they are in violation of their contract if they fail to acquire the remaining 15%, the founder now has complete control to dictate any price they want.
That is the scheme described: how to short squeeze pensions who do not even have shorts for fun and profit.

It seems the S&P 500 indices only take the free-float shares into account when calculating weights:S&P DJI’s market cap-weighted indices are float-adjusted – the number of shares outstanding is reduced to exclude closely held shares from the index calculation because such shares are not available to investors.

Yes, but not the Nasdaq-100 [1] which added the "Fast Entry" rule listed right there in section 2 literally this February because SpaceX is demanding immediate inclusion into the Nasdaq-100 as a condition for listing on the Nasdaq instead of the NYSE.[1] https://indexes.nasdaqomx.com/docs/NDX_Consultation-February... Section 3

If they choose to chase that pie, then they alone should be the ones to bear the burden, including any/all reactions from passive investors.
Passive investors should (ideally) switch to another index if they wish to not be involved in this IPO. The decision of how they should invest is theirs, and if they're not happy with this index, they should move to another index: Their money talks louder than any posturing that could ever be put out.
