If they're employees, they get a lot of rights and protections that maybe aren't common at all in the US. Companies like Uber (and e.g. construction companies, marketing agencies, etc) will push people to become self-employed so that the employer has no obligations or responsibilities whatsoever to the employee. This will allow them to out-compete the companies (like Black Cab in London) heavily, at the cost of the workers.
