No, I don't. Every contract has two parties. Elon did not want to go through with the contract, the other party forced them to abide by the agreement (Twitter's shareholders, which funnily enough, many of Twitter's employees are counted among).
Everyone knew what selling twitter to elon meant for the employees and the company. There were rumors of mass layoffs weeks ago. It was forced through still anyway.
So in addition to Elon, everyone that cashed out of twitter is responsible for what's happening to the company now and all the employees that allowed the company to become fat and bloated are responsible too.
