(FYI, CRSP doesn't exist anymore)

CRSP adjusted their methodology prior to SpaceX IPO being announced. It's part of a larger discussion about what the purpose of an index is and how people invest. Vanguard is not out to screw people's retirement up (quite the opposite really). Anyone is welcome to be part of the discussion, but it's hard to get anyone to take you seriously if you only come out of the woodwork when something "bad" is about to happen.
