I write for two Uber oriented websites, so know quite a bit about the company as I write upwards of 15 articles per week on Uber.
There really is no right or wrong here as taxi drivers and the industry do not have a divine right to monpolize a market, consumers deserve choice and Uber provides it. That said, the company flies in the face of regulations under the guise that it is a technology company and its drivers are merely freelancers. Fair enough, but this means the company operates illegally in virtually every market it is in, which in turn means uninsured drivers. Seattle's decision to allow Uber drivers to form a union could change a few things for the company, while local governments are slowly finding ways to stop the company's expansion.
That said, if Uber plans to come here, then it will probably thrive as it has everywhere else. I welcome it because it gives more choice, plus I think the taxi drivers in this city are collectively poor at their job (come at me supporters of the industry).
