It's like saying that the drivers aren't employees because Uber doesn't provide health benefits.
Companies routinely get in trouble for forcing their employees to buy their own equipment. But it still happens all the time because of the power imbalance even when they're employees.
This is one of the many thing which makes all this such an existential threat to Lyft/Uber. Even just when it comes to minimum wage there will be a huge fight because so many drivers make less than that when the equipment is taken into account
Uber also is a technology company just like eBay.
If Uber riders were able to pick the driver they wanted and drivers were able to design their own advertisement page the riders see as well as being able to negotiate with the rider directly without loosing the Uber's platform protection, I would agree.
The relationship between customer-seller is just much different than rider-ridee.
If Uber wants to be treated as a marketplace and sidestep this new law, it needs to make significant changes - if drivers are truly independent contractors they should be able to set their own prices at a minimum.
