Which is why, when you're selling a company for hundreds of millions of dollars in unvested stock, you don't sign a deal where the buyer can fire you for "mere accusations of a potential crime". Uber lost the lawsuit with Google and had to pay a quarter of a billion dollars. I'm sure their contract said something like "if you have materially misrepresented information to us that results in us getting sued for a quarter of a billion dollars, we can fire you".

Even if the contract doesn't say anything like that, they can still fire you. Misrepresenting information as part of contract negotiation is fraud.
