The due-diligence-waive thing isn't really relevant according to Matt Levine, who has been pretty consistent about this for months (see the thread @ https://twitter.com/matt_levine/status/1545151445057536001). A couple of choice tweets here:
"""
the reason that elon musk can't get out of the deal over the bots thing is not that he "waived due diligence." it's that he SIGNED A BINDING AGREEMENT TO BUY TWITTER, and that agreement does not have any outs for "i think there are too many bots.
"""
... and ...
"""
yes i know that this is a small petty thing. but part of my point is that even if he had demanded extensive due diligence, and done it, and then signed the agreement, we'd be in the same place. the waiver or not of due diligence doesn't matter; what matters is we're past that.
