So they did tweak the rule for total market indexes, just not the "curated" ones.

In the summary table of "proposed changes, current methodology, and result", the result column is "no change" for all rows. What rule tweak are you referring to?

Edit: Ah I see it now. Separate tables for S&P cap-based indices and their other indices.

it makes sense for a total market index as it's a "total market" index. Given the purpose of the SP500, it makes less sense but I still see the argument. Grift or not, morals or not, an index shouldn't care. An index shouldn't care any more than Excel should care about the morality of evaluating a formula. It just tracks what it is defined to track. Leave it to the individual index tracking funds to apply a philosophy to their investments.
