I worked at a company that provided products to uber, lyft and doordash drivers, and personally interviewed well over 200 drivers, (along with having access to detailed data on a much larger dataset). The vast majority of drivers we talked to did not feel like they were being 'exploited' and generally liked the flexibility of the gig economy. Most workers were part time, working to supplement income from other jobs or in between other gigs, in fact when i was there, most drivers worked less than 6 months before stopping. I would say these people have a much better sense of whether they are being exploited than people who are not in their shoes.
There was a small but important minority (we called them 'professionals') for whom driving had become their full time profession (most were not cab drivers before) who were perpetually annoyed by uber and their main gripes tended to be the changing promotions systems, and algorithmic changes that reduced/limited profitable rides (like airport pickups) and just general loss of control.
