Yes, some stuff does break, and some categories suck more than others, and sometimes Wirecutter gets it wrong. But I have not seen anyone point to any meaningful evidence that Wirecutter is improperly biased or is anything worse than simply a product review site that does it best but sometimes gets it wrong.
I've used Wirecutter top picks and have never been burnt. This entire thread is people bashing Wirecutter without providing any examples of bad products.
