Thanks for the quote of denial because in theory, 20% is not a majority so he is right that he can't monopolize the firm.
However, in practice, he shows his intent to gain more control by continuing saying:
"Basically,
I’m trying to accomplish an outcome where Tesla can operate at its best, free from as much distraction and short-term thinking as possible, and where there is as little change for all of our investors..."
He basically reminds that it's the singular "I" that wants to steer the direction of the firm!
Of course to gain control he wants to:
1) reduce distraction
2) reduce short-term complaints
3) have "little change" in here means less choice, less flexibility once going private.
The problem with filtering out public input is Tesla would continue to have an interior free of cup holders, free of coat hooks, free of foldable feature for second row seats for Model X, free of ceiling grab handles for seniors like myself due to his minimalization philosophy.
It's a trade off.
But in the end, I think the Board would give Elon Musk what he wants: More controls because they believe he can accomplish more efficiently if there's fewer oppositions or those who keep questioning his every small step such as "Where are my ceiling grab handles?"
