SpaceX going in the index is fine but I think changing the rule to make it different from other stocks is iffy and was at the request of Musk. There's a Patrick Boyle vid talking about it https://youtu.be/8rS3fTbC7TE

My financial advisor might have recommended that expensive fund to me because it was a good idea, even though he also received kickbacks from the fund for doing so. The point of being a trustworthy index is to avoid the perception of conflicted interest.
