Interestingly enough, Vanguard voted against the package originally in 2018, and Black Rock voted for it (according to nytimes https://www.nytimes.com/2024/06/12/business/tesla-elon-musk-...)

    Tesla’s second-largest shareholder, Vanguard, voted against the pay deal in 2018. BlackRock, the third largest, voted for it. Both declined to say how they were voting this time.

I actually think that for VTSAX manages, the fact that they have to vote is sort of a liability for them. My guess is that they would rather not vote at all. They own the whole market anyway, and should only care about tracking the underlying index as accurate as possible with as low fees as possible, its bureaucratic. Now they have to publicly vote in a dubious popularity contest and take sides in a battle they don't care about.

For the record, Vanguard also has significant interest in the success of all Tesla competitors that are part of the index.

Did Vanguard officially stated that they have "significant amount of trust in Musk"? They are not Cathy Woods.
