My take on this is no they don't. As long as they are truthful they only report on the quality of the product and prevent many people of spending a lot of money from losing it by buying something that doesn't work.
If your product is shit your company does not deserve to be shielded from the backlash, this is the core of (classic) capitalism after all.
Maybe the people who lose their job when they go under. That being said we shouldn’t prop up a bad business just because people might lose their livelihood
There's a different way to look at companies. They're not just profit-making entities. They are ways of organizing people to accomplish things nobody could do on their own. The profit is just there to keep the lights on and pay everyone a living wage.
Our current system doesn't encourage that approach, but that's just a problem with the current system.
