> waving a smartphone in the face of regulators
At least for government, that wasn't a smartphone he was waving. It was a stack of something with drawings of U.S. Presidents on it, sort of greenish.

In that case, the smartphones were the ones in the public's hands: Uber ran an effective media campaign, including paid-for editorials in major newspapers (and I'm guessing elsewhere) about how great it is to be an Uber driver, and, AFAICT, astroturfing in online forums and social media. Uber was a darling of the business world, a paragon of SV and American innovation. Not so long ago, you couldn't say anything negative about Uber on HN without being voted down to oblivion, and the talking points were repeated in every discussion.
