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.
Honest reviews prevent bad reviews from others and returns. They should be embraced for what they are and a blueprint for what you’ve done well and where there is room for improvement.
