REUTERS/Pedro NunesLISBON, Nov 2 (Reuters) - Mark MacGann, the whistleblower behind the so-called Uber Files, said on Wednesday that the ride-hailing company seemed to be taking steps toward improving its work culture but that its business model was still "absolutely" unsustainable.
MacGann said Uber's current CEO, Dara Khosrowshahi, and his executive team "have done a lot of good things, but they have so, so far to go."
"My message to Uber is: 'you've done well, (but) you can do it so much better (because) the current model is absolutely not sustainable,'" MacGann told a news conference during Europe's largest tech conference, the Web Summit, in Lisbon.
He said Uber recently reiterated that the "core of its business model is independent contractors, since everybody wants to be self-employed, everybody wants flexibility."
"Uber is pumping tens of millions of dollars in Europe, United States, other parts of the world fighting legislation," he said.
