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.
Reviewer opinions on both Humane and Fisker are pretty consistently negative so this isn’t some mean YouTuber with an axe to grind situation.
The products are bad and people shouldn’t waste their hard earned money and time on them. Venture Capital firms may lose money, but that comes with the territory. Not every venture is a win.
