Maybe, I think he doesn't want to buy at all. With TSLA down almost 50% since he proposed to buy it based on loans against his stocks it would be very expensive for him at any price now.
But I mean who knows, your guess is as good as mine. I think it was an impulse buy and now he has regrets.
So, does he not want to buy, or not under current market conditions? :)
He doesn't have loans against his Tesla stock anymore. He replaced those.
On what grounds would Twitter possibly offer a discount? He made an offer, filed with the SEC, and they accepted. As far as I understand he's currently contractually obligated to go through with it.
For example, to avoid protracted litigation. Last year, Tiffany aggreed to a slightly lower purchase price as well.
