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.
I wonder if he would have made the same review if it was made by apple/samsung/google.
He did something similar for the Apple VR headset. Not as extreme, but probably because the product was not that shit.
