Why are they being fleeced? If people didn't want to buy SpaceX they could buy some other ETF that doesn't include it. If there's enough of a demand I'm sure ETFs will be offered which include all the big indexed stocks except SpaceX.
Its fleecing because it basically takes everybody's money and gives it to support musk's money loser xai. SpaceX net profit 8 billion per year (previous years much less) and Xai was net losing 1.5 billion per quarter.
