> spend a ton of money fighting for years
Twitter is worth $28b and Musk's offer was $44b - a $16bn delta. The most annual revenue that a single law firm in the US has made is about $4bn.[1]
Any amount Twitter could spend on lawyers is nothing compared to what they stand to make by winning.
If you're accounting for whatever "toll" it takes on the company's leadership and employee morale, $16bn is about 2.75 years of operating expenses. Even if you assume every employee is operating at 50% mental capacity the entire time, it still makes sense to fight as long as it's over in <= 5 years.
