Sounds like Uber was up to shenanigans when they whipped up the internet rage machine. There was some conversation going on between Uber and Cheh, I don't think we're getting the full story here.
Given that this amendment would have severely hurt Uber, I'm definitely inclined to believe them over Cheh on this.
Looks like 'earned media' to me, free mentions in the press for throwing a fit.
Not supporting the amendment, of course- just saying.
