That ignores the actual issue here, which is the change in rules. Index funds already seek to own the entire market, and when most people chose these index funds there were rules about when newly listed stocks get purchased by the funds. And now those rules are being changed.

Index funds generally try to match the performance of the index, but most are not required to hold the same companies as the index itself does. They typically do, but managers often have choices.
