If you're still following, I want to give a more thorough response, since I don't think my other one got to the core of your point.

I think your point is that it's common practice to not mention all kinds of add-ons when listing prices, so there's nothing particularly unusual about Uber doing it, even if we'd prefer everyone to agree to stop doing it.

But even so, I think there's a big difference: in the case of taxes (retail or labor), there's a valid defense: "I don't know tax rates in your municipality", "I don't know how many deductions you have or what your family income is". Even so, when paying a vendor, you know how much you're deducting from their payments for yourself, so you don't really have an excuse for reporting a figure that includes a part that you know you have to personally take out.

The scumminess would be more obvious if Uber e.g. claimed that rides in a certain interval would get a 10% bonus, without also mentioning that they increased their take to cover it all. It would no however, be scumy if they simply failed to mention that "oh, this might push you into a higher tax bracket".
