Knowing the possible shitstorm it would cause, Twitter upper management sold the company anyway. Not that they care, they got fabulously wealthy off the deal.
Shareholders were being offered a very nice premium on the stock price, so Twitter upper management would have been awash in shareholder lawsuits if they'd rejected the deal.
Essentially, the Twitter board was snookered once Musk made a serious offer.
"A Saudi prince who is among Twitter’s major shareholders scoffed at Musk’s offer in a Thursday tweet. Al Waleed bin Talal said he would reject Musk’s overtures because he didn’t believe $43 billion “comes close to the intrinsic value of Twitter, given its growth prospects."
Not selling the at the price he offered would have been massively violating their fiduciary duty. Twitter stock would probably be worth like $20-30 given the current market versus the $54 offered.
