Ah, but then a user might throw an Internet Fit(tm) and cause a public outcry about ratings being manipulated by Uber etc. etc.

There's no way to easily verify how companies are actually calculatign the displayed ratings, and I doubt the average user would care or be savvy enough to find out. I assume it's a given most services see the input ratings as a personal indicator modulated by how reliable/benevolant/... each user is. Reddit votes, for example, are fairly nonlinear and visibility priority is even more complicated.
