Thanks for providing the numbers and your take on the situation.
I think we come away with quite different reactions to the same facts: I view it as telling that Uber spent roughly four times what the taxi lobby spent, but most of the conversational focus regarding spending targets the taxi lobby - one of many widespread biases in which some bits of the for-hire transportation debate get more frequently talked about and others usually overlooked.
The (legitimately real) rank and file support and skewed discussion focus which Uber's ad/lobbying money has bought them isn't my idea of grassroots backlash, even if it unwittingly enlists the grassroots in their PR campaign.
No doubt the taxi lobby is pushing their interests just like Uber pushes theirs. Neither set of industry lobbyists is truly looking out for the citizens.
But when the conversation they've shaped pairs "bought the mayor and City Council" for the less-spending party with "created a grassroots backlash" for the more-spending party, I can only marvel impressed and saddened at Uber PR's effectiveness.
In most cities, the local taxi lobby plus the citizens who oppose Uber/Lyft/Juno/Gett for normal public policy reasons are even more outclassed against a major VC-funded global would-be monopolist like Uber than NYC managed. I'm impressed at de Blasio and City Council for holding firm.
(As you can tell, I'm no fan of these companies for several reasons, but explaining those reasons substantively would be a huge tangent.)
