True, Musk's lawyers haven't accused Twitter of lying. They've said Twitter is withholding information that Musk is entitled to (I had to go read the letter). And yeah, the contract gives him very broad rights:

> Section 6.4 Access to Information; Confidentiality. Upon reasonable notice, the Company shall (and shall cause each of its Subsidiaries to) ... furnish promptly ... all information concerning the business ... as may reasonably be requested ... for any reasonable business purpose related to the consummation of the transaction...

I think it makes perfect sense that any financier will ask "How many users does Twitter have?" And that entitles him to this information.
