I'm guessing enough accounts were deleted to get the attention of Uber's CEO, Travis Kalanick.
Via The Daily Beast:
Uber CEO Travis Kalanick left President Trump's business advisory council on Thursday over the administration's ban on refugees and visitors from Muslim countries, according to a memo obtained by Recode.
Uber faced an enormous backlash from users after Kalanick initially said that he would continue to engage with Trump after the president's recent executive order.
In a memo to his employees, obtained by The New York Times, Kalanick wrote: “Earlier today I spoke briefly with the president about the immigration executive order and its issues for our community. I also let him know that I would not be able to participate on his economic council. Joining the group was not meant to be an endorsement of the president or his agenda but unfortunately it has been misinterpreted to be exactly that.”
See, folks? Taking action can result in change.
