Twitter would pocket a billion dollars - ~5x its net cash flow for last year - why on earth would it sell for _less_ when it can invest that cash in just about anything? He'd be buying the company years of runway to build... whatever it wants - at that point I'd invest in twitter as soon as Musk's check cleared.

This isn't a renegotiation, this is him paying points on his mortgage for a lower rate - but where the points paid go towards the previous owners either way.
