Elon Musk made an offer to Twitter to buy the company. Twitter's board accepted. Apparently Twitter had some obligations in the fine print to disclose certain aspects of their userbase (there is a question about how many accounts are fake, aka robots or "bots"). Mr. Musk asserts Twitter won't provide the data and has walked away from the deal. Twitter is suing him to enforce the agreement.

What caught my eye is the last part. Mr. Musk is asserting that the data he was seeking will now come out as part of the discovery phase. Is there anything Twitter can do to avoid disclosing the data, or would it be considered too material to the case to avoid?
