I’m an enthusiastic amateur home chef. I have ordered some of these “trash” whetstones.
My knives get sharp. They aren’t damaged. The whetstone works over time.
If you are like a knife artisan, yeah I guess Amazon won’t work for you. But I’m guessing the results work for 99.9% of people.
I could also make a more graphic analogy, but I don't think anybody needs to read that.
But when I just need some basic household thing and don’t want to become an expert on the category, I often shop from other retailers where I can just be pretty sure they aren’t selling garbage.
Any porcelain measuring spoon someone like Crate and Barrel sells is probably a decent porcelain measuring spoon, but if I buy that on Amazon, I have to worry about which brands are legit so I don’t end up getting a spoon with porcelain-look paint that will flake off or something like that.
A marketplace where almost anybody can sell almost anything has a completely different level of trust than a store where professional buyer is making a conscious decision about what products they should carry - the presence of many low quality products dilutes the entire marketplace, even the quality products from legitimate brands
(I'm still having good results from amazon but I can understand 'entirely enshittified' as an opinion from people getting a similar thing there)
