Uber Eats censors negative customer reviews of restaurants -- is this a violation of consumer protection laws?

Basically, if you make an order on Uber Eats and love it, and rate the restaurant 5 stars, the platform allows you write all your praises for the food; and then it'll get published as an official review for that restaurant on its Uber Eats page.

However, if you did not like the food and rate it poorly, you are not even given the ability to write anything about it. You just get several preset prompts to select from ("Food was cold," "Portions were small," etc.), and your negative review will never get published!

This obviously skews the perception of restaurants from the vantage point of consumers, who will only see the positive reviews for them. They will see no critical reviews which might make them think better of making a purchase.

So is Uber unlawfully misrepresenting what it's offering? Surely there must be something in the law to compel Uber to either have a fair customer review process, or cease showing any reviews at all if they're dishonest and cherry-picked. Because imagine if Amazon did something similar and only showed positive reviews of the products they sell!

Indeed, the whole censorship process even makes the platform's star rating suspect -- since restaurants on the Uber Eats platform routinely have a higher average star rating than on the restaurant's analogues Google page. It makes me think that not only does Uber Eats not publish negative reviews, but they don't even incorporate them into the star-rating.
