Which of Uber's competitors will suffer under the new regulations for contractors in Ontario?

If you don't know what I'm referring to, it's basically the same thing as what's established in British Columbia, New York, and California for gig workers so they can get paid and treated better (at least in theory ye). I heavily suspect that Uber lobbied for this to happen as a way to kill off their competitors to get bigger market share, and as an excuse to get rid of the surplus amount of people they did hire over the years, with the benefiting of workers as simply good PR. Since I'm a bike courier in a suburb, this will benefit me, but for car couriers and rideshare drivers they will (according to themselves on the UberEats subreddit) are gonna suffer financially in Ontario due to the new legislation, which I'm sure Uber wants so they quit or work less.
