Check your impressions about Uber - they have never pretended to be a ridesharing service. Uber fares are metered and non-negotiable. The controversy with Uber is that it straddles livery car service and traditional taxis, and that makes its legal position fuzzy.

Uber is distinctly different from what the article talks about here: Sidecar for example does project itself as a "ridesharing" service, where fares are determined by the rider (with not-very-subtle "suggestions" by the service) and optional (though of course, not really).

I'm a fan of upsetting the corrupt and outdated taxicab industry, but at the same time I have few sympathies for Sidecar and the like when governments rightly call them out on their bullshit: they are not ridesharing services, no matter how dumb they play.
