Lets think about this for second:
Here is a person that feels committed to the truth and does not sign a deal because it would create the impression he did wrong but he is convinced he did not.
The SEC is suing him because they believe he did not tell the truth at the time of his tweet. They tell him "either you sign here and leave the position for 2 years or we will make sure you will never be a CEO of a public company again"
His answer is that signing would be like telling not the truth. The SEC turns around and sues him for sticking for what he believes is the truth.
Also the SEC makes the claim to protect shareholders. If Elon believed at the time of the tweet that it was correct even if maybe it was not then he did tell the truth and not mislead anybody. He was maybe not right with his assumption but acted according to the truth.
When the SEC sues Elon and the SP falls 10% and later it turns out that the SEC believe they have been right to do so but did not win would that mean the did damage to the shareholders as they claim Elon did to them?
"Under the terms of the deal, Musk and Tesla would have had to pay a nominal fine, and he would not have had to admit any guilt. However, the settlement would have barred Musk as chairman for two years and would require Tesla to appoint two new independent directors, reported CNBC's David Faber, citing sources.
Musk reportedly refused to sign the deal because he felt that by settling he would not be truthful to himself, and he wouldn't have been able to live with the idea that he agreed to accept a settlement and any blemish associated with that, the sources said."

: Tesla's Musk pulled plug on settlement with SEC at last minute
I would be surprised if Elon did not do a thorough review of the situation and a clear statement of his lawyers after they reviewed his evidence. Lawyers are paranoid if it comes to that situations. Elons replied after the news broke was carefully and well written from lawyers and I guess prepared up front. So this did not came with surprise.
They will have played out their options in a war room meeting and came to the conclusion with the backing from the board that its better for Teslas mission if they don't sign the agreement and go through the lawsuit to win it.
So all signs are pointing in the direction that this is a well thought through strategy and we should trust them that its the right thing to do.
They way this plays out here should give us confidence that there is more evidence than the SEC believes.
Its been a coincides decision and not a desperate and ill thought action from one person.
