On the contrary, house brand products are great for consumers. Rather than having to figure out if they can trust a brand for a product category that they really don't care about, they can just buy the house brand knowing that a certain minimum level of quality exists. This is why Amazon Basics products are so popular on Amazon: consumers know that, at the very least, Amazon can be sued, a form of recourse that is not available with most of the smaller brands and sellers on their platform.
This is me. I bought an AmazonBasics product initially, a phone cable, thinking it would be crap. It wasn't. So I bought another one, a set of HDMI cables. They weren't crap either! Then I bought AmazonBasics wash cloths as a joke. They were quite nice! Now I find myself shopping around the AmazonBasics section first. I still find it amusing in a "Spaceballs, the flamethrower!" kind of way.
