I agree. I'm a fan of "the price is the price," with all of the various overhead expenditures being factored into that price. There's not a line item for their app developers, nor a charge for their server hosting...
Lyft's ain't free, it just uses the legal fiction of a "suggested donation" as a fairly transparent attempt to avoid taxicab regulations in some cities.
...or a more strategic "cut prices to lock people into our service, and then up the prices". Uber cuts the prices of UberX to attract traffic away from Lyft, Sidecar, etc, and then raises prices and relies on people not having the inertia to go back to other apps/suppliers and shop around.
Right, can I opt out of that fee? There's a link to a new axe design trending on HN at the moment; how about I buy one of those and bring it with me to guarantee my own safety and opt out of that dollar fee?
Line-iteming a fee feels like it opens it up to negotiation.
