Doesn't sound anything like that. It would be like if "Ask HN: Who's Hiring?" was asked why they didn't ensure that the hiring was evenly distributed among (say) races. They're just a forum, a place where people can post stuff. They can't guarantee that the people posting are of that distribution unless they themselves post it.
In this case, Uber is just a forum where people post ride availability and people look for ride availability.
It's not an outrageous argument to make, but it clearly didn't take. Presumably Uber will have to ensure there are sufficient UberWAV available in any region they offer normal services.
Uber enforces standards on drivers and cars to use their platform -- and take around 30% or more per ride. This is obviously completely different from HN's "Who's Hiring?" threads.
Well, the standards can't be that important. If you post the r-word in your job listing you're not going to get listed. But the payment may do the trick.
But then you have the opposite problem, don't you? Ford or Exxon is making a significant profit from the activity too. The former may even be imposing standards -- some modern cars have a limp-mode if they detect a fault -- and they had a lot to do with whether the vehicle is wheelchair-accessible.
