Almost. Musk uses an ellipsis in his copy in the text that elides some text that is rather detrimental to his claims:
> In furtherance of its purposes, the corporation shall engage in any lawful act of activity for which nonprofit corporations may be organized under the General Corporation Law of Delaware.
> The certificate of incorporation shall set forth [..] the nature of the business or purposes to be conducted or promoted. It shall be sufficient to state [..] that the purpose of the corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of Delaware [..].
And if the argument is "its just boilerplate, the court shouldn't take it seriously", that's an argument I can get behind for something like a EULA - but not for an article incorporating a non-profit whose signatories include incredibly rich and high-profile individuals, who either had their lawyers comb over this contract, or should've done so. "I didn't realize what I was signing" is not a particularly valid excuse coming from Elon Musk.
