And how much can the US government censor you versus companies?

There's tradeoffs. The government, at least, has to abide by the constitution. Companies don't have to abide by jack shit.

That means infinite censorship, searches and seizures, discrimination, you name it.

We have SOME protection. Very few, but they're there. But if Uber was charging black people 0.50 cents more on average because their pricing model has some biases baked in, would anyone do anything?

Yes, because race is a protected class.

If they were charging wealthy people 0.50 more on average because the model showed that they don't care about price that much, they would be fine.

> Yes, because race is a protected class.

No: because Uber doesn't have to tell you how their model works and they probably don't even know.

Doesn't matter. If you can convincingly argue that the effect is discrimination based on race, you have a civil rights claim.
