I think the fact that Twitter is a platform of international significance can have a lot of negative legal consequences for the company, especially if you consider the fact that a lot of international employees that represented Twitter in different locations were fired (partially illegally). This could have the consequence that Twitter gets geo-blocked in some countries, partially or completely. The fishy legal situation also influences companies decisions to work with Twitter as a company (advertising). The "worst" thing that can happen is that Elon Musk loses a lot of money, which is already happening and probably will continue to happen, if he proceeds to run the company by doing what he wants without perspective.
