KINDA, SORTA, EVENTUALLY: Uber says it will stop using Greyball to evade authorities.

“We are expressly prohibiting its use to target action by local regulators going forward,” Sullivan said.

The tool seeks about a dozen data points on a new user in a specific market, like whether the Uber app is opened repeatedly in or around municipal offices, which credit card is linked to the account, and any publicly available information about the new user on social media. If the data suggests the new user is a regulator in a market where Uber is not permitted, the company will present that user false information about where Uber rides are, showing ghost cars or no cars in the area.

Uber said on Friday that Greyball wasn’t just targeting regulators—it used the tool to prevent riders who might aim “to physically harm drivers,” as well as prevent dispatching rides to competitors who might try to disrupt service. Uber also affirmed that it used Greyball to shut down “opponents who collude with officials on secret ‘stings’ meant to entrap drivers.”

But now Uber is walking back on that last use case for Greyball. Sullivan told the BBC this week that “it would take some time” to enforce the company’s new prohibition on using Greyball to blackball regulators, although the tool will still be used to root out other users that might try to violate Uber’s terms of service.

From the sound of this, Uber drivers will remain just a corporate wink and a nod away from using Greyball to avoid police stings.
