Restauranteurs opt-in to their relationship with Uber Eats. If they feel they aren't getting compensated fairly, they can opt-out.

It feels quite condescending that you think you need to protect restaurants from Uber when restaurants are already capable of dissociating from Uber. You're essentially saying restaurant owners are too dumb to know what's best for them, so you need to make decisions for them.

This is not how it works. There is a network effect. If everybody uses Uber Eats then as a restaurant owner you have no choice but to opt-in. Talk to some restaurant owners.

And to make a more general remark: the free market doesn't always have the desired effect. See for example Net Neutrality which wouldn't exist if the free market had its way.
