Musk hired good lawyers to make best case that can be made when there is no case, but Musk is going to lose this.

The cost of playing chicken against Twitter board is relatively cheap at the beginning. If they don't flinch he must suck it up. I doubt he can afford to drag this for years because he will just drag Twitter valuation down and is still going to have it.

Twitter board can't just give up this deal that is now super good for shareholders. It's their fiduciary duty at this point. They get sued if they don't see this trough.
