And again, there's no ambiguity. She says she has extensive records of this behavior. That's not something she can really walk back. In a situation where one person's word is pitted against another's, the most reliable way to buy credibility is precommitment. By writing the article that she wrote, she made a massive precommitment. She will be screwed if Uber takes her to court and she can't back up her claims. Uber, meanwhile, has said "We're looking into it." Precommitment is about cutting off your options. Uber has done the opposite.
So we have one side that just cashed out options for credibility, and one side that wants to wait and see. If you're trying to assess the situation rationally, there's only one correct play here.
