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.
Good. Make better products and support them after you made them.
If your company sounds scammy and you say it can do things it can’t, I hope your company burns before you burn customers who believed your lies
