I have heard from several friends I trust that Wirecutter is no longer very reliable since being acquired by the New York Times in 2016, and that their Wirecutter-advised purchases have become pretty mediocre in the last year or two.
I'd be interested in people making some of that case, as answers to this post, including things like talking about purchases they made or basic errors they found in the reviews, as I don't have strong, publicly verifiable evidence on this at the minute.
This is a biased post, I'm writing this with the hope of helping propagate this info if it's true, which I suspect it is but am not confident of. Please give whatever answers you feel are most relevant.
This basically means they are perfectly achieving their goal, right? Wirecutter's goal isn't to find the best product, it's to find the best product at a reasonable price. If you're a power user, you'll be willing to buy better and more expensive stuff.
